3 wheeler keeps dying

[Bigredrocket]

I have an 84 200s and it doesn't start on the first oull everytime. (I wish it did) any help with that would be appreciated. But after it starts it idles fine and runs good for about 15 mi Utes. Then when I'm sitting still it just dies. But it's always after riding it for about 15 minutes. Any I out would help. Thanks

Try running it with the gas cap loose. It sounds like the vent in the cap is corroded shut. You have to have air above liquid for positive flow. When the vent fails, fuel will draw from the tank until the pressure goes negative then it will actually draw fuel from the carb back in to the tank.

Thanks! I Would go test it now but my throttle cable just broke. So when I get a new one I'll test it out and post the update here.
