whats the stock compression supposed to be on the air cooled 50?
varies from 125 psi to 135 psi
thank you, time for a rebuild ive got just under 100 although not bad but would rather be more
general rule on any combustable engine is atleast 100psi..
much less and it won't run very good if at all...
