We have a Carbide 150 cart that just stopped running while my son was driving it. It doesn't have but about 80 hours on it. It has spark, compression and fuel, but will not even try to fire. I took it to a local motorcycle mechanic. He isn't familiar with them but I downloaded all the manuals.

He checked out all the things I had and checked valve adjustments timing, etc. It still will not fire. I even tried a little starting fluid but it won't even make an attempt to backfire or anything.

Does anyone have a clue about this, or had it happen to them?

Thanks
