bought a small boat it came with a 3 hp sea horse,doesn’t appear to have reverse,recoil was all tangled up,got that working,gas tank was empty but looks cleanish,a litte dry dust ,not sure when it last ran ,wasn’t going use it,but i see it could be collectable ,was going clean the tank and let it rip,this old engine is alot different then any i have seen,i was looking where to plug the tank in for a few miutes,before i figured out it was built in,seems to have good compression,main question what fuel mix 24 to one?and i don’t see any reverse
