when you try to attempt to start the atv, what does the plug look like. is it wet with fuel? can you confirm that it sparks by haveing the plug off, and grounding it while turning it over?
yes, strong spark, bike will start with exhaust off, but exhaust not clogged.
yes wet with fuel.
does moveing the fuel valve from PRIME, to any other position seem to make any difference? was the carb you replaced brand new? or off of a used atv? when you do get it to run, does it seem to start to soot over the spark plug?
yes carb brand new, does not soot over plug, fuel valve from prime to on, does not change anything.
With exhaust off and prime thru carb, holding throttle wide open will start right up, and run above idle for 30 sec and then starts to die unless you choke it.
Hello,As Eric said it is not getting aproper fuel/air mixture for some reason.Do you still need assistance?Have you checked if the carb bowlhas fuel in it?
