Anybody (Spud in particular!) know what a safe thickness is for a home-cooked 346xp (NE) cylinder gasket for maximum squish?

 

 

:001_smile:

 

Clean the carbon off the squish band and the top of the piston and it can be removed completely. This should give another 15 - 20 psi but if measuring with a gauge, give the engine a few light turns with the starter before yanking it over hard. The mod can take out the gauge schrader valve very easily:blushing:

 

Use a high temp liguid gasket to seal the base and I personally check vac and pressure afterwards:thumbup:

 

Worth opening up the Muffler exhaust hole as well, a very easy mod to do with a dremmel:thumbup:
