If you went from a stock jet to a larger main jet to fix it that means you just added more fuel to cover up a vacuum leak. With the stock muffler and airbox it should run with the stock jet. If all was well and you run a larger main with the stock muffler and airbox it should run pig rich. The large (37) jet should be used with a header pipe and filter kit.
I put a header pipe on and modified the airbox and it runs fine with the 38 jet. Even if there is an air leak I don’t know where it would be coming from cause I did just about everything to fix one.
@@JPkartz Understood. I think we run mains that are too big in the stock carbs. I ran a 38 with my built 224 and the plug looked like I was running rich. And that was a bored carb. It now has a VM22 clone. Your 5/8 drill bit for the venturi is a good idea. I got some reaming tool to open mine. Ruined one carb trying to go too big.
@@Deucealive75ive never really been precise with jetting lol. My go kart has a stage one kit with a jet drilled out with a 1/16 drill bit (yes it’s extremely rich)
The easiest way to tell is the shape of the valve cover. Hemi motors have a rectangle cast valve cover, while Non hemi motors have a stamped valve cover.
@@JPkartz not yet Im working on another or and ima buy a cr250 soon so i’m being a little bit careful with money rn and the speed a goes is still pretty good

So how do you spot a hemi 212 vs a regular 212? Cause that looks like the one on my bike
