So I poured some straight Seafoam into the fuel lines. Let it sit there for a few hours. Took a little while to start and when it did puffed smoke. try to ride and soon as any amount of throttle is applied no matter how small it dies. it idles just fine. right now the engine is fully warmed up. so I know that it has to be running regular fuel now. but still soon as I apply the throttle it dies. the choke open or closed doesn't matter.
