So the mikuni that came on truck when i bought it started sucking air from everywhere.

I had some credit at junk yard picked up another oem that says "remanufactured". Truck drives like a different breed. Downshifts has some power! Freeway speeds are a breeze.

I have dialed pretty close but need advice on final tweak. Runs and drives well with choke on. Drives good once warm, but when Come to idle has miss about every 10-15s. Exhaust smells like eggs (brand new cat).

What does everyone think? Too lean or rich?

BTW: ignition all new
