I am a new Buggie owner with a GS Storm. It has been running great untill recently. The problem I just came about is the fuel keeps flowing backward into the tank. I can get it started after I hold my finger over the pipe to prime. But, when I run the throttle wide open it bogs out until I backoff the throttle. If I gradually give it throttle it will run while picking up speed. I also noticed when I stop my buggie the fuel flows backward into the tank.Then I have to do the finger over the pipe trick to get it started after its hot. I appreciate the help..... Thanks N.[&o]

It is most likely that you are running to rich still. read the current thread on tuning a Hyper 21. the principles are the same.

Sounds like your HSN is way too lean.. richen by 1/2 turn and try it again .. the fuel running back into the tank is probably because the hsn is stopping the fuel from flowing inot the carb ..

Thanks Massivemods!

That did it, I have been adjusting the HSN leaner since it is broken in now. Also the change of fuels could have had an effect. I am still running 20% just different brand. I hope the fuel change wont make problems for me.

Awesome glad to be of help !! Every time you change fuels you will get a different response from the engine.. . usually different temps.. check tuning every time you change fuel ..

temps shouldnt worry you too much. just make sure that theyre's enough smoke coming out and just a little bit of oil.
