Hello i have a 1986 Honda Fourtrax Foreman 350A i just recently bought a new carb for it from a atc 350x works good but atv just constantly blows gas and air out the back of the carb
i tried to adjust the valves to stock specs 0.08 0.003 on intake and exhuast on the compression stroke on TDC i have tried almost everything to get this bike right it will not run with the airbox boot on bogs
and full throttle is very stuttery like cutting in and out spark plug gap is at 0.7mm fuel pump is 1 to 4 psi air screw is 2 turns
burns out your eyeballs have a video if needed
