I've seen guy's start themselves and kart take off, but no idea what caused it.
Not because I know anything about them, I didn't think it was a good idea when I saw them start to try it, but by the time I spoke up they didn't hear me and it was to lateThat’ll always be a no for me when it comes to two strokes. Having to hold the throttle wide open to get an alky smoker to start while not in the kart spells disaster
I ran my water pump backwards on my 250 and i guess piston got red and the motor kept running away from me.it wound up melting pistonI’ve heard horror stories about open 2 cycles running away. Seals going bad, carb throttle getting stuck etc. Has anyone experienced this on the track and found a good way to shut it down before damage occurs and or wrecking? Do’s and do nots?
Prc chassis have there throttle spring return bolted to the floor pan, not a really good design when the floor pan flexes it will pull the throttle open on yea. Found that out on the kart stand.
Yes, on DD when you push start them if the only thing you can do if check the cable and eveything like the arm often, but when you push start them once they stick open before you even jump into your seat there is no way you can reach the filter or even anything you set to cut the ignition.I run a thick foam filter that I can reach over and choke the carb. It's happened a few times over the years and it worked everytime.
Well if set correctly and nothing fails it won't take off on its own and the only issue is if you are not fast enough it dies or won't start. Now if it somethings messes up and it starts and takes off fast you'd better not try getting i the kart.You gotta be faster getting in.
If it's a high horsepower motor like a UAS I'd put a kill switch on and good brakes
