Okay, not a chainsaw, but with the knowledge in this section of the site I figured it was the place to be.I have a BR550 blower that's acting funny. It starts easily, idles like a dream, and runs perfectly to about 3/4 throttle. At that point it sounds to me (based on my BR600) like it's running right at full throttle and purring like a pussycat. BUT, if I pull that last 1/4 or so it just falls on it's ass and goes back down to very near an idle state.
It's doesn't die out, but gets very close. It's honestly nearly like an idle condition, but just a hair rougher.The specs I found only show an idle RPM, so I haven't yet bothered putting a tach on it at the max RPM or compared actual numbers to my BR600.Anyway, here's where I'm at; I disassembled & cleaned the carb, adjusted the metering lever (needed a slight raise), and put the H&L screws back in at factory settings which is where they were at when I started. The air filter is clean. The fuel filter is new.
The spark plug is good & has a correct gap. None of the above made even the slightest change.
The only thing left that I know to check is the valve gap, but it's been my experience that an out-of-adjustment valve would result in a poorly running machine in general, not just at the last leg of of high throttle.Anybody else have experience with this? Any opinions on what I should try/check next? Thank you for the suggestions all.I've adjusted valves on many 4-Mix engines and do have the specially shaped Stihl feeler gauge. I'll eventually try to adjust them, it's just not acting like that's the problem; compression is where it should be, and it doesn't run rough at all up through a high RPM - smoothe as can be - it just instantly falls on it's face with the last bit of trigger.I suppose the coil could be suspect, but would a bad coil allow it to run well up through a pretty high RPM and hold steady, but reduce down to an idle-like speed immediately at full throttle? I have an old coil off of a BR600 - since they use the same one I would swap that out to see.I'll check the fuel lines more closely this evening and perhaps do a pressure check.Thanks. If it's a choppy running it's usually I've had several that seemed like the rev limiter was kicking in at lower rpmthan it was suppose to and that was a coil issue.If it's a bogging down issue replace richen the high up to 2-3 turns and see if that works had some that needed a ton of fuel on thehigh side. If that doesn't work replace the carb.

They're around $40I only had to adjust valves usually on high hour commercially used, it's a low hour machine that's unlikelyit needs to be done.The BR550/600 have been really reliable and only usually see these couple things wrong with them.

Well, I finally had a chance to work on the BR550 this evening. I was hoping to be able to report back on what the cause of the issue was.
The good news is that it's running like new again. The bad news is that I have no idea what was causing the issue. I hate it when this happens, especially when it's a piece of equipment I'm planning to sell.The carb on this blower has no limiters and I first verified that I had properly set them at factory specs after the cleaning - they were spot on. Ran it again, no improvement.
Second I swapped the coil out with a known good one. Ran it again, no improvement. Then I checked the fuel line - not compromised.
Then I checked/adjusted the valves. Both were just a hair tight - arguable whether they needed adjustment at all, but the way I was taught was so that the feeler gauge has a similar resistance to if you were to push a pin through a piece of paper. Ran it again, no improvement.

Just for the hell of it I checked the gap on the plug. It was a tad on the heavy side, so I closed it down to the.020. Ran it again, no change.Then, due to the suggestion from beermeatguns above I decided to play with the carb settings. I leaned the H about 1/2 turn and YAHTZEE! Revved right up through the full trigger pull and held solid. Then I held the trigger and and slowly richened the H back up to see if I could re-create the problem. I backed it out another full turn with virtually no change in operation.
So, I returned it to the factory H spec where it had been - 3.5 turns out - and it proceeded to run just like it should. I'm only grasping at straws here, but all I can figure is that there was perhaps a slight blockage in the H jet that I didn't get when cleaning the carb and messing around with it just happened to have cleared it out? Thoughts?Thanks for all of the suggestions.
The Start menu in Windows 10 is one of the most cherished and iconic features of Microsoft’s operating systems. And while it seems strange to have such powerful emotions for a mere software feature, the mass opprobrium against the Start menu-less Windows 8 shows that people will viciously argue for their right to use it. But what if the Start menu stops working?Whether your Start menu has disappeared, simply isn’t responding to your clicks, or you get the dreaded “Critical Error” message, we’re here to help you with you Start menu woes.Related.
The Obvious StuffWhenever you get any kind of error relating to various features in Windows not working, the first thing to do (aside from rebooting your PC) is check for corrupted files using the system file checker which will automatically try to fix any errors in Windows’ system files.To do this, open the Command Prompt ( Win + R, then type cmd) and type sfc /scannow. A scan will check Windows for corrupted files, then repair them if possible.If that fails, still in the Command Prompt, use the “Deployment Imaging and Servicing Management” tool which can repair corruptions that were preventing SFC from doing its job. In the Command Prompt, type. Dism /online /cleanup -image /restorehealthThis will run the DISM tool.
After, run another SFC scan to fix any outstanding errors.If your Start menu’s still not working after this, it’s time to dig deeper. Fix 1: Make a Registry TweakA solution to the Start menu not working cropped up some months ago, and quite a few people are reporting success with it. Pdf pendidikan pancasila karya kaelan.
It’ll require you to tweak your registry, so make sure to first.Once you’ve done that, open the registry editor by hitting Win + R and entering regedit into the box.In the registry editor, navigate to the key. HKEYLOCALMACHINESYSTEMCurrentControlSetServicesWpnUserServiceDouble-click “Start” in the right-hand pane and change the “Value” here to 4. Reboot your PC and you’re good to go.Fix 2: Restart Windows ExplorerThe next simplest thing to try is restarting the Windows Explorer process which is responsible for the Start menu, among plenty of other things, on Windows 10.
Press Ctrl + Shift + Escape on your keyboard to open the Task Manager. Next, click “More details” if you’re in the simple view, then under the “Processes” tab scroll down to “Windows Explorer,” right-click it and click “Restart.”Fix 3: Run Application Identity ServiceThe Application Identity Service in Windows 10 uses a service called Applocker to decide which applications are and aren’t allowed to run on your PC.
For the most part you don’t need to touch this, as it generally knows what’s right for your PC, but forcing it to run when you’re experiencing the Start menu problem can help fix them.To run the Application Identity Service, press Win + R, type services.msc into the box, then in the Services windows right-click Application Identity and click Start. Reboot your PC, and your Start menu should be up and running again.Fix 4: Stop Sign-in Setting up DeviceIf you’ve noticed a pattern of your Start Menu misbehaving each time you have a Windows Update, or simply when you restart your PC, then a couple of people have suggested that this could be the solution.Go to “Settings - Accounts - Sign-in” options then scroll down to “Privacy” and switch the “Use my sign-in info” slider to “Off”. As you’ll discover in the next fix, your Start menu not working could be connected to your Windows account, oddly, so separating your account from your PC startup process can help.Fix 5: Create New Admin AccountSome people find that their Start menu stops functioning properly after bigger Windows updates. If you’re one of these people, then a tried and tested solution is to create a new Windows admin account, make sure that the Start menu is working on it, then transfer all your files over.To do this, press Ctrl + Shift + Esc to open Task Manager, then click “File - Run new task” and type. Net user yourname yourpassword /addinto the box, where “yourname” is what you want to name the account, and “yourpassword” is the password you want for the account.
Tick the checkbox to make it an administrator account, then click “OK.”Log in to the new account. If the Start menu is showing, you’re in business.

To transfer your settings and apps over to the new account, log back in to your old account, then go to “Control Panel - System - Advanced system settings.” Click the “Advanced” tab, then under “User Profiles” click “Settings.” Select your newly created account from the list and click “Copy To.”Fix 6: Reinstall Your Windows AppsWindows apps may have nice features like Skype’s mini-window that lets you talk to people while getting on with other stuff, but they’ve been known to bug out Windows from time to time. Pinning down the app responsible for the mess can take a while, so there is a convenient command in Windows that lets you reinstall every Windows app simultaneously. (It’s almost as if Microsoft was prepared for people to have this problem!)This is a good chance to get acquainted with the PowerShell, which is essentially a supercharged version of the Command Prompt. Click Start, type powershell, then right-click PowerShell in the search results and click “Run as administrator.”Once you’re in, type the following and hit Enter. Other users have reported that anti-virus programs like Avast, Malwarebytes, and various third-party Windows Store apps can also cause the problem, so it’s worth uninstalling some of those one by one to see which is the culprit.
We’re Just Getting StartedThese are the best-known ways to get your Start menu back in order, though with the problem having so many different possible sources, there’s always a chance that something else has fixed it for you. Has one of our fixes helped you, or have you discovered your own solution to a broken Start menu? Let us know in the comments!This article was updated in August 2018. I had this problem like many others, after 3 days of trying different steps, I found that somehow the actual window of the start menu shrunk itself to not visible. Easiest way to test is to toggle “Use Start Full Screen” under “Personalization/Start”.

If your menu shows up full screen, then it must be working. If it is working, toggle it back to off. If it doesn’t work again, click the icon once so it highlights itself, then move your cursor up a few pixels till you see an arrow cursor and simply resize the start menu back to where you like it.Note, I have a Microsoft Surface and I ran across this problem when disconnecting the Surface from my extra monitors. My guess is that something happened when it entered tablet mode.Hope this save someone the trouble I went through.
