Hey everyone just picked up a 4 zinger. When i went to get it it ran and started on second pull but quickly died. Wouldnt start again when i got it home. Air filter deteriorated im guessing it got sucked up in the engine. Also throttle has about half inch of free play and choke is sticky at the lever i have to push it back down in. Im new to 2 strokes i work on cat equipment daily tho. Just looking for some tips to get it up and running. Also air box was full of old gas. Thank you!
