SOMEBODY GAVE ME THIS SLED. IT STARTS AND RUNS. IT DIES WHEN U TRY TO RIDE. I REBUILT THE CARB(WALBRO),IT WAS REALLY CLEAN. REPLACED THE CRANK SEAL ON THE CLUTH SIDE CHANGED THE FUEL FILTER. IT ACTS LIKE IT IS RUNNING OUT OF GAS. IT HAS NEW PLUGS ALSO.
Do you mean it dies after a little while when riding, or dies when you try to make it move? If it dies after running a little, it could be a bad coil, I had an old 72 Cheetah that started great, ran fine, but when warmed up, would die like running out of gas, then not restart for a while. Sold it to a guy who then replaced the coils, and it ran like new. That style sled should have external coils, so replacing them should be easy enough to do.
