I need a little assistance on how I should adjust my carb. Sometimes when I floor the engine from idle it will cut out and die. The engine will start right back up and it doesnt do it all the time but it occasionally will. Also, I pulled my sparkplug and it has a little carbon on it like it might be running rich. Other than this issue it appears to be running good but maybe I just dont know any better. Any ideas on what adjustment I should start with?

Oh yeah my set up is a Muzzy dual exhaust, K&N intake, DJ175 Main, Mikuni 50, Washers flipped on the stock needle and I beleive the A/F screw 1.5 turns out (I believe).

Don't know what your elevation or temps are, but start here:

Try a MIKUNI 160 main, 45 pilot for sure(50 IS too big), 2.5 turns out on a/f screw.

Invest in an A/F guage; worth every dime when trying to tune!!

FWIW. C-Ya!!
