I’ve got a dead BG55 in my shop right now and I think I’ll check out that area when I start to work on it to see if the issue still exists in a subsequent version.
When you work on a power head , how do you tune it w/o the load of an accessory? I set my idle a little fast and carb a little rich. Have a great holiday, waiting for the next one.
You are my new hero. I have had a lot of Stihl stuff coming in. Wow. It seems to me now that the Stihl's are plugging off at the muffler screen. more than other makes??
I agree 100%. my personal opinion is those screen mesh are a bit too tight. Even with the best oil and running full blast they still seem to clog. Maybe a better catalytic converter would do a better job of burning up the carbon instead of leaving it at the spark arresting screen. Anyways, Thanks so much for stopping by my channel brother Bruce 👍
Interesting, but I don’t think you actually addressed the cause of the failure. From my viewer perspective it appears as though the forces acting on the throttle trigger are not direct, but rather offset a little bit, forcing the trigger slightly to the right. This has possibly caused wear on either the side of the trigger where it mounts to the axle upon which it rotates or on the side of the axle itself, or both. I think I saw some wear on the latter. I would have installed a very thin washer on the axle post before replacing the trigger. You can probably tell if this is the case by looking at how much free space there is on either side of the trigger once the case is reassembled. If I’m correct it won’t be centered but will have less space on the right side.
Well done sir Dave
Thank you sir, i had the exact same problem! 😅
nice diagnostic

I follow what you are saying spot on. The washer is a great idea.
