Is there any issues with the tether cord or kill switch causing spontaneous spark problems? Especially if you broke a tab off your kill switch and can rotate the red knob right around? I broke it a few weeks before I started to have problems with it though. Starts up when its cold and when I have time to look at it. Stops sparking after I shut it off out in the trails. My buddy has the same sled I can use to swap parts to find the problem but it always sparks and runs when I have a chance. Its an 05 440. Can I just take out the kill switch? I dont need it anyways figure id start there. What do you guys think?
