Poulan gasket delete (?)

[pelhamjeff]

Hi guys, I'm putting a 4000 piston and cylinder on a craftman badged 3400. I tore up both base gaskets and was trying to decide weather to try to find one or make one and then I got to thinking about leaving it out. I remember reading a post somewhere about how some saws get a power increase just by deleting the gasket, while others (the 359 husky was the example given) don't benefit from it at all. Both these saws had 130 PSI before I got started. What would all you Poulan experts do here? Any advise appreciated!

Lots have done it. The squish on those is typically around .040" so it will raise compression some.

Use a gas resistant sealer like Yamabond or Permatex Motoseal

I got one in with pulled gasket and grey sealer used. Might be Threebond 1184 1194 or one of the other like Tim mentions or even motoseal.
