Yes its another chinese quad that won't start.

Here's the story - bought it from a coworker for the kids. Was working fine, then gas tank started to leak. Top of carb had been damaged so throttle cable had a mind of its own at times. I bought a new gas tank and carb. Installed them both no big deal. Got it to start and my son took it for a test lap around the house. Restarted it one more time in the garage just to be sure.

Next day - all it will do now is crank. There is fuel in the carb, i can smell it in the exhaust. There is spark. I have 150psi compression via compression gauge. The kill switch is in the right position. I even tried putting a squirt of carb cleaner in spark plug hole. Last night i spent 2 hours messing with the thing still can't get it to fire off. I checked all the electrical connections, pulled apart the kill switch on the handlebars which seems to work fine. The atv will crank over with kill switch in either position??? Is that normal?

During my two hours last night i put the old carb back on even....no dice. I even tried adjust the air/fuel mix screw...no change.

Any and all ideas are appreciated!

 

It was the damn spark plug, crappy autolite, put in NGK and it fired up.

It has some alarm/remote start garbage on there. Can that be bypassed???

 

Yes you can bypass the switch. You have to jump some wires in the harness. Sometimes the manual shows you. If it’s working and running I would leave it though.
