Hello, I'm new to the forums and this is my first post. Im having problems with my scrambler. I bought it a few weeks back for 500$ the guy said it needed a stator and a ignition switch he was using a wire to bypass the switch. I replaced the battery and tried it, it wasn't getting spark so I plugged up the ignition switch he had and it started getting spark I don't know why he thought the switch was bad. I put it all back together and it ran perfect. The CV joint was clicking and it finally snapped so I replaced it. It was running perfect and I ran it out of gas, it sat for 3 days and I filled it up with gas and rode it for around 25 minutes and i got off with it running to check something and it shut off. I got back on turned it on and it wouldn't idle without me giving it gas. So I drove it back home and right when I let off the gas it shut off. After that it wouldn't start.I let it sit over night and it ran in the morning for about 10 seconds and shut off, every so often it would run. I thought it was the carb so I took it off and cleaned it and it didn't help. It has weak spark and it backfires so loud when I choke it and try to start it. I'm completely stumped and can't figure it out.
