i just recently put my bike in the shop had piston rings checked and valves were adjusted.when i went to pick up my quad he said i am getting hit and miss spark so i decided to take the quad home and try to figure out myself besides payin a fortune now i have no power at all but when i first got it i could crank all day and would not fire up even push start would not turn over for nothing i am pretty new to working and figureing out stuff on quads so any help would be greatly appreciated..!thank you iin advance

check your throttle cable man, if its bent at all it wont allow your quad to start. i had that problem a few weeks ago.
