Chainsaw Repair

Nice looking project. What kind of reeds are you putting in it?

I was thinking you may want to loc tite studs into the crankcase and use aluminum lock nuts on top.
I was at a contest in 1989 and was helping out a competitor fix his two Marcel Vincent built 084 and 090. The 090 lean seized and the 084 was starting to. Found out the saws had long cap bolts like yours and weren't staying tight. Crankcase threads were giving out from a couple of removals. So we fabbed up 4 new studs with nuts.

I have some longer bolts ordered so I can use all threads in the case. I may go to studs if these give problems when I add lock washers. Hadn't planned to actually run it yet but I couldn't resist when I got the carb on. I don't know what reeds it actually has in it. Look like Boyeson that's on ebay. It's a 6 petal set up.
