Question about ATVs
Its time to check a few things.. First - remove the air filter and see if it runs ok then... if not... have the carburetor professionally cleaned and set... does it run ok now? .. have you installed a new spark plug? .. do that.. if it is still not running ok.. time to check the compression using a compression gauge that screws into the spark plug hole...
Innova Compression Tester
Your engine should pump at LEAST 120PSI. Once you have screwed the gauge in and lightly seated the o-ring.. turn the engine over for at least 5-8 seconds with the throttle WIDE OPEN... 120psi. minimum... if you are not getting very very close to this.... its time to find out why??... it might be that the valves are too tight... but find out why?... this is probably the reason it won't run..
