I just picked up a cheap ported 12a with good compression but unknown running condition. Trying to dig up a little info before I tear into it. So has any one heard of JP racing(carved in the top)? I am googling but see nothing.

 

Never heard of them. Maybe it was the builders garage/shop name???

 

Bet I know the previous owner's initials...

 

LOL, thats what I was thinking, but thought I would ask.

Oh well, if I can find the socket for the flywheel local I will be cracking it open to check specs and the "porting"

 

Maybe PeeJay had one too many beers and spelled his name wrong... lol

Is there mud caked all over the oil pan.... that would be a dead give away..
