i just fixed the carb flushed out the crap. i need to know the air screw setting i have it set at 1 and a 1/2 turns out. but it runs a bit ruff with slow gas but if i give it a hard snap of gas it sounds strong.i got the bike not running so i dont know how it ran before i got it.

 

I'm not 100% sure but I believe it is at 2 1/4

 

Main Jet: 112.5, Main air jet: 1.6, Jet needle 5L10, Needle Position: #3, Pilot Jet: 20, Pilot Air Jet: 60, PILOT SCREW # OF TURNS: 1.5, Valve Seat: 1.8, Starter Jet: 80. These are for stock configurations. Not sure what they all mean, but hope it helps.

 

thanks for the help i will try 2 1/4 and see if it runs good if not back to 1 and 1/2 i will change the spark plug to and see if that helps to.
