Preadtor 212 help

#1
I built a drag bike from a nitro 44 frame. The motor is a predator 212 that I rebuilt.

- DJ-114X ARC top plate/throttle hookup
- 6934 ARC billet air filter adaptor
- DJ-1257 Choke hold
- Fuel Pump
- 6877 Pulse inlet fitting
- 6899 Angled air filter
- 5' fuel hose
- DJ-1420 Chain guard/heat shield
- 18-930HJ Header, muffler and clamp
- DJ-1056 Valve Springs
- ARC Billet Connecting Rod with bearing inserts
- ARC SFI Certified Billet Flywheel
- DJ-1103 BP-2 Cam
- DJ-2227 .625 Gas Carb

I got it all put together but it doesn't idle right. I'm running gas. The engine surges and wants to jump forward at random. Any ideas on how I can fix this problem? I think it might be the fuel air mixture is too high, meaning too much fuel not enough air, but I have no idea how to adjust it. Any ideas will be greatly appreciated, Thanks. :hang::helpsmilie::helpsmilie::helpsmilie:
