Fuel Blowing Out Carb Soaking Filter

[BRI98]

I have a hyper.21 8 port in a used buggy i just picked up . I test drove it and it ran ok a little sluggish on the bottom so I went to the OFNA site and got their factory settings for the carb and started fresh. I dont know where I went wrong but it will start it will idle until the air filter fills up with fuel then it dies. any throttle will kill it. if remove the air filter and fire it up a fog of fuel pumps out of the carb I have no clue what is up. one more thing when I test drove it the pull starter was in tact on the test drive the recoil broke so I hav been using a starter box and along with the fog coming from the carb the recoil is filling up with fuel I am new at NITRO cars and I am stumped any help would be great.

:flamer:

I had the smae problem with fuel in the air filter and fuel spraying out of the car. My engine/carb was tuned yay too rich. A couple of 1/4 turns on the HSV and my problem was solved.

This will cause hydrolock(hard to pull the starter), hydrolock+pullstart, sometimes = a broken pull start.

Try lewaning up the High speed needle valve 1/4 a turn at a time until the fuel in the filter, and the spary out the carb goes away.

Be careful starting your motor on the bump box with that much fuel in your engine. It could bend a connecting rod.

Good luck

if its the HSN it shouldnt flood the engine and cause a hydrlock LSN too rich will cause hydrolock though

HSV will do it as well, at least on the XTM .18 ...

Thank you for the replys, it turned out to be WAY rich on both needles. The factory settings are not even close. they said 4 out on main and 3.5 turns past flush on lsn. I called OFNA tech support they said lsn 1 turn IN from flush that was much closer ,hsn turned out to be 2 3/4 out. I dont know how you could even brak it in with the factory settings
