Looking for some help to try and identify an A&M gas engine that i got in a recent transaction. The owner couldnt remember the size. It is stamped a&m and the only numbers i can find are 49zn2 and 37H8w or it could be 37HBW. There is a V1B also on the case. I need to get an ignition set up for it. I am new to gas engines so any help here would be greatly appreciated. Thanks
