I have seen many lean 2-stroke failures and the p/c on this edger doesn't look anything like that. As a matter of fact, the p/c look great. I am hoping a new set of rings will wake it up. Just waiting on them to get here.

New rings will probably help, while you're at it, replace the crankshaft seals. They are a possible culprit, preventing the engine from developing enough vacuum to draw the proper amount of air/fuel into the crankcase.

I got the edger apart this weekend and replaced the rings. I also checked the crank seals while I was in there and they were fine. After getting it back together, my edger is reborn! It runs well and has the same power that it used to. I just forgot what a pain a dual ring, 25cc p/c setup is to work with. I also wish that Stihl would run the cylinder bolts from the top, like most chainsaws. That way, you wouldn't have to remove the crankcase from the clutch.

Oh, I also cracked the plastic intake manifold (Stihl calls it a flange, I believe) when I was reassembling it. I put some silicone on it for now and will stop by the dealer tomorrow for a new one. But, for about $15 and some sweat equity, I got it going.

Stihl FC75

I can not get my FC75 started, I changed the spark plug, air filers and poured fresh True Fuel in it. I will not start, I removed the spark plug wire and I see it's getting a spark but will not crank. Also, I cleaned the spark arrestor screen.What else should I try?

Is the spark arrestor screen still in? Is it clogged? If an engine cannot get rid of it's exhaust, it acts very, very tired!!!!
