If you are getting output or blowby back through the carb then the valve is not sealing properly or the piston cylinder fit is no good.

If the engine is running the correct direction at higher speeds the valve is in the position. You can kind of thak this info to determin which way the valve is set to run.

Intake is intake, front or rear. just turn the crank and compare the opening to the one shown. Hope this helps.
