My son rides his 4 wheeler daily, he was riding 3 days ago quite a bit shut off and when tried restarting it will start but shuts down within 10-15 seconds. Almost as if it's not getting gas the fuel line was kinked so his grandfather changed lines, bypassed the shut-off direct to the carb, checked the engine oil changed the spark plug, checked brake fluid as I was told that there are certain safety switches that might affect it but really at a loss here. We've been noticing that occasionally upon starting it will go forward or reverse while being in neutral. He shuts it off and waits a minute starts and it's fine. If anyone has any suggestions what to try next I'd greatly appreciate it. Carb was cleaned about a month ago because we got some bad gas(full of water) it had been running great since except that occasional start and immediatly go in reverse not sure if that's connected to the issue now but 🤷 thank you in advance
