Four years ago I was watching this video and realized you were rebuilding a chainsaw exactly like mine. I could not believe that my piston looked as bad as yours but I was so wrong. I rebuilt the whole thing watching your videos- carburetor included - and everything came together like clockwork. I depend on that saw and since the rebuild, it has never let me down. Thanks very much!

Donny, I'm really glad this video was still up. Seven years ago I rebuilt my 55 watching you, and last fall I just knew it was time to do it again. It's been my go-to saw, and with a new top end and carb, I'm sure it will stay that way. Thanks!

Just a quick tip from a machinist who has to use allen wrenches daily. Sometimes when we get a bolt thats tight or in an awkward place, well get a small metal tube and put it on the short end of the wrench and this way you get lots of leverage and it might be a bit easier than a pair of pliers. But your method obviously works too! I like the videos.

Hello, really nice videos, im an engine tuner (2-4 strokes) and, you should put the wrist pin clip at either 12 or 6 o clock, if 3 or 9, they can snap off their groove because of the piston acceleration, especially on high speed engines ;-)

When you put the piston into the cylinder, you pointed out a little pin that you lined the gap of the ring with. Does that pin hold the ring in place so it can't rotate? I've never seen such a pin in auto engines. Is that little pin unique to this kind of engine?

@donyboy73 your husq/stihl dealer should give you a contact, canada is another continent to me. :D I'm not an opponent of cheap parts, but someone already partially pointed out - it's chrome plated but should be nikasil. nickel matrix plating gives the endurance and torture tolerance. bit more expensive but worth it. chrome is very brittle and can flake off, but nickel matrix is actually impregnated silicon carbide. OEM pistons are also forged, not cast.

I have overhaled the carb but still wont start. Is the cause now likely to be piston or ring damage caused by possible overheating? Watching your vid now has given me confidence to dissasemble or can I check compression first (if so how is this best done?)
