I'm having trouble with a air leak between the carb and rubber boot, any fixes, New boot. Seems like a crappy design. Steve

You could try some sealant like Yamabond, Hondabond, Motoseal.
Edit: Disregard that, I was thinking it was between the boot and cylinder.

There should be a gasket between the carb and boot. That should fix the problem. It's actually a good design and jonsered was ahead of the time with these saws.
Also I see that you are from MN, depending on where I'd be happy to help
I don't think they have a gasket between the boot and the carb, but I could be wrong. I think it it like a 372, just the boot, plastic flange and the support ring. If its an aftermarket boot the support ring may not be getting pressed all the way in when you tighten the carb up.
Yes that support ring doesn't want to go down into the aftermarket rubber boot like it should, will have to work on that more. Its a good saw except the intake design, having to take the cylinder off the get a new boot on and the really small sealing surface on the inside of the carb bolts. Steve
