Carb adjustment issues
 

I have tried using two carbs and have ended up with the same results. The only way i can fight this 110ST quad is to adjust the air mix screw a 1/4 turn out and the idle screw 1/2 turn out with the choke on with lots of starting fluid. once started and warm I can adjust the A-mix out to 1 1/2 and the idle 1 1/2. seems to run better with the choke on. I have great spark and about 80 psi on the cylinder. what do I do to make this start easier and run better

what?
 

adjust valves, reclean carb/jets, check for air leaks. i.e. cracked plastic intake/missing O-rings on intake at carb/etc.... please be conservative with starting fluid:eek:. the quad can get very used to and addicted to the ETHER BUNNY:lmao:. no wonder you're losing compression. it's starting to wear the rings. keep an eye on oil consumption and any smoke when running.

well come to find out I only have 48psi. looks like I will be replacing rings
