I have a cub set up. Jim smarts personal 421. Not really looking to sell but if the offer is good.

What would you do to fix the issue? Run a fuel pump?

Stupid phone. Slower...shoot me a text. 8145058437

Would maybe bumping to c-14 help?

And thanks slower than you......that's some good info there.

Both cylinders and is a 4 mil long rod. Its your semi typical 421 cub.

And my jetting is about the same as other similar setups. Messed with timing and jetting both. Even tried different mixing oil. Frustration from a year that could've been better

Jetting is 170 mains. 52 pilots. Dgh needles. Only thing I really changed this year is pipes and domes. The plugs burnt a light chocolate

Tried that. I tried timing from 75 thousandths all the way up to 110. It actually occurred less with more timing. The motor runs strong and other than the plug issues, guys at the track know my machine when it ran, it hauled ass. Pulled off my fastest time yet at the beginning of the year. And I can only imagine the power it would have if I could figure up what this stupid little issue is.

I'm running c-12 from vp. Timing is at 96 thousandths advanced. I run a pvl. 68 mm cub. Vf4s porting initially done by passion and then re done because it was crap. Port timing is to mat shearer specs. Domes are from hjr. 18cc. About 165-175 on compression and 55 thousandths on my squish clearance. I am not exactly sure of the squish angle nor the percentage it takes up. I run 500ft dirt and by the finish of my second pass......one or both plugs are smashed shut.
