Hello. Recently, I switched out the cylinder on my two stroke, and after doing so, I have a really bad vacuum leak. The RPMs pretty high, as if i'm holding the throttle half way, and in neutral, it skyrockets. As of right now, I have sealed the carb mounting spot with heat resistant caulk, made a new head gasket out of silicone gasket maker, as well as made the carb level. I have also made a gasket for inbetween the intake manifold and the intake hole on the cylinder. Anyone know what else I should do? Will gasket maker be strong enough for a head? I can add pictures if anyone requests any. Thank you for any help.
