268-fuel between pot and gasket

[miker]

having probs with starting husky 268 ,runs for a bit, erratic idle,then stops and cant restart,so took pot off and found fuel between pot and the gasket??

the gasket is very thin , just wonder if A- would this be my running/starting problem and B will a new gasket solve the problem of fuel getting where it shouldnt:confused1:

Carb or cylinder base gasket? neither should have fuel in between them unless it may have spread by capillary action when you took the saw apart.

 

The answer is to re-assemble and pressure check!

Thats not right - you will have to check the mating surface - small imperfections can be ground out with fine emery on a flat surface - the crankcase mating surface is a different matter - the base gaskets are generally 0.5mm - a thinner gasket probably means that someone has done a bit of cylinder lowering:001_rolleyes:

 

A little smear of blue liquid gasket will help seal the joint, a pressure check will always tell you if you have a good sealed crankcase or not.

 

Symptoms of an air leak are intermittent idle, higher than normal top end revs and an idle that keeps increasing over time.
