Poulan 42.Ill take a pic of mine and post it later.Never mind,ill do it know.I didnt take a pic of the head with the webs and uindentations but mine match.What plane is it on?By chance an EF-Yak.
Scott brillellis one of his first engines was the poulan 42.I traded him a few items for one.This is another ive had.
He had a combo with an EF-Yak.But i dont remember if it was the 42,46,or both.The 46 used a rubber boot so you had to make an adaptor to fit.The 42 bolts right on to the cylinder like the pic.
