You should replace the gasket, they wont run properly if theres an air leak. The feeler has a narrow tip, I was going to modify a standard one but really not worth the effort! Clearances should be checked on a cold engine. Turn to TDC and check its the compression stroke with both rockers free to move.

Valve Clearance Setting Kit for Stihl FS90, FS91 Brushcutters - OEM No. 4180 007 1005 | L&S Engineers WWW.LSENGINEERS.CO.UK Valve clearance setting kit Genuine Stihl Part OEM Part No. 4180 007 1005 Suitable for the following Stihl Machines: FS83, FS83T, FS90, FS90R, FS100... Mistake.. 67p!

Perhaps your problem is not with Stihl but instead, trusting your local dealer to service them, who likely think they can sell you a new machine instead of an easy fix. The Br800 is a 4 mix engine, generally they just need the valves adjusted which is a very simple, easy, 10 minute job, you need a gaset/feeler gauge set which costs all of 50p.

It does look like a significant fungus infection at the base and possibly roots. If it were me I would ask the local council tree officer to inspect, they could likely identify it. It looks significant enough I'd suggest they give permission for removal.

If its a weak machine I could weld a baffle to reduce the size of the hole by an inch. Sounds like these are running a bit near their maximum and feeding it easier work might double its life?

Great to know someone that has done a weld repair. I was also thinking reinforcement needed. You welded in situ? We dont want to strip it. I assume your Kempi is a mig? I have a Sherman 200A tig/stick welder, I'm no good at mig! Unsure to use basic 6013/er70 or the better 7018/er80, stronger but more likely to crack... Might be better if we find a pro welder to do it. We are not trying to be cheap but £5k for a replacement fitted flywheel is too much... Would you have a photo of the Jensen? If not I'll search for it when I get home. I doubt the fan blades themselves see much force but looks as though they reinforce the flywheel. When it works they are a great machine ( not that I have experience of others) and will swallow up anything that fits in the hole. Perhaps we should be more careful what we feed it?

My friend has problems with his ST6P and this thread came up. Has anyone had problems with cracks on the flywheel fan blade welds? They want to replace the flywheel but its extremely expensive. Its a 2017. The main issue, the feed roller snapped and is getting repaired. I am wondering if this can be welded in situ, grind out the cracks and re weld. I'm not a professional welder but can do TIG and stick. I am unsure about something this size however - it should likely be preheated to avoid cracking, and very difficult to heat something that size, in place, without over heating anything else. It will be a very heavy lump so no chance of us stripping it out ourselves.

£29.. may be worth a try as amazon returns are easy.. https://www.amazon.co.uk/Housing-Handle-STIHL-MS440-Chainsaw/dp/B07BW3Z1QX

A cordless ratchet is a great tool, they dont have the hammer or power of an impact wrench so are not going to strip any heads. Great when theres bad access to a bolt. If the heads are covered in shite, you need to clean that, whatever tool your using.

500i? This is all my mate uses when his MS151 is too small.

Done. Video did not work out as it was pointing at my feet! I've never been good with videos. Much of it was already removed which they did with hand saws, must have taken ages. I started somewhere halfway up. Gentle angled cuts then touch in the middle, and it often pings off. Once I had a cut all along I wedged it futher from the wall with some cuttings, that gave clearance to cut along the bottom and then the top with no risk to the chain. I dont have a suitable ladder here, so couldnt properly reach the roof. Carefull nibbling away at the ivy got the wall cleared. My chain was already a little blunt and I did touch a few times early on, it'll sharpen up ok. I always use cheap chains for this sort of job. I used the 020T.

Can you put some pictures up? I would not choose Stihl for any battery tools, from what I have seen they are well behind other power tool manufacturers. Having searched the part number, the motor appears to be a cheapy 775 size DC motor.This is not a proper tool motor - but the sort of thing you expect from a Lidl. These motors overheat for fun, not suitable for this sort of work. You may be able to easily swap it. The difficulty will be removing the gear from the motor shaft and re installing on a new motor. They are likely a shrink/interferance/press fit. The problem is it will likely happen again. I would suggest a different brand with brushless motor. Stihls homeowner grade battery tools are junk.

Noticed this a few times, is there a way to turn it off and just show me all posts in date order?

You cant just fell your neighbours garden trees without their permission. I believe council are only relevant if TPO or conservation area, but still requires the owners permission. You can trim back to your boundry but thats it. Without permission would be tresspass, criminal damage and possibly more. Not to mention, if there is a genuine reason for removal, example tree being dangerous, the owner should be paying for its maintence.

If the top is struggling that would suggest to me a root problem or rot preventing adequate nutrients from being absorbed. Have you a photo at the base of the tree?
