So, I just made my first MB. I used a 66cc grubbe skyhawk 2-stroke on a greenline beach cruiser. I installed everything a couple days ago and rode it around a little but I had some huge tensioner problems. All the bolts already stripped on the kit tensioner just from adjusting a few times. I'm currently trying out a ghost ring tensioner and it works great as long you have it shoved in the chain far enough.
When I first built the engine it would start up fine every time. First try it would usually start up and I could ride it right away. Yesterday the engine started doing this thing where you had to try starting the engine a few times before it would actually stay on. I would ride it with the clutch in, let it out, and the engine would start and then slowly shut off. If I pulled the clutch in once it started it would turn off instantly. If I give it gas, it might rev a little, but not enough to keep it going. After trying to start it maybe six times like this it finally kicks in and stays on. Let it warm up a little and it still runs great. This process has happened a couple times now and seems to happen any time the engine has been off for about and hour or more. I'm pretty sure this isn't what should be happening and I'm wondering if anyone has an idea of what it could be.
I also replaced the kill switch yesterday morning with a home-made toggle switch (on-off). The toggle switch is an inline blue wire kill switch and it still works great to kill the engine. I used speaker wire from an old stereo I had to connect the blue wires to it. Could this be what's causing the problem? Thanks for all your help.
