hello all, just picked up a 4 cylinder engine it is a two stoke and the case has a cast mark says ACME 10940 i believe the number is? it has a mag on the flywheel end and a prop hub on the front. it is single spark plug and has a small carb on it. will try to find a number on the carb tomorrow. if picture comes thru see if any of you can give me insight into what i have please. thank you.
