fuel backing up...
 

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! :D

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.
