RE: Engine I.D.
I really didn't want to throw a wrench into all the good work, but the base numbers differ considerably, and the carb has a Walbro plate on it.
Ralph, this is the engine that I described about a month ago without the pics, and you were looking to see if you had one laying around to match the numbers with. I was running it with a 22-10 prop since it didn't seem to like a 24 inch. It's head is quite a bit larger than any of the 3.2's I've seen.
Thanks for all the help and light you can shed on the subject. I am going to have to send it out for repair/check up/ or a re-build soon to put some life back into it. It does run pretty smooth, even with the age. Whatever the age may be. A little short on compression, though.
