I have a JLO with a Warbro carb. When I get the fuel flowing to the carb, itdosen't stop!! It floods the engine, fouls the plug, dies, and keeps running fuel through the carb untill I shut off the fuel. Any ideas on how to fix this?? Thank you. Chad |

Check the fuel return hose that returns unused fuel back to the fuel tank. Is the return nozzle stopped up? Use a spray carb cleaner with the tiny spray tube that comes with the can to spray cleaner thru the carb inlet. Cleaner should exit the carb thru the return orifice. No return = carb flooding. |

Chad,
It sounds to me that your floats are stuck in the float bowl. On the Walbro on my JLO, you can simply take off the bottom of the float bowl and inspect why this may be happening. It could be a worn needle-seat interface, perhaps their is varnish build-up on the float hinge, or something similar to this that's preventing the needle from closing in the seat. (It's just like when a toilet runs and runs and runs...) This is likely pretty inexpensive to get a new needle-seat just in case. I've never seen a "return line" that could get clogged up; at least not on a six wheeler...
Good luck!

Hey Mike, Thanks for the post.
that was my first thought, but there is no fuel bowl on this carb. It has plates that are layered up. The first has a filter, the 2nd is a gasket with reed valves and the 3rd has a diafram that opens a needle valve, but no float. |

between the diaphram and needle valve is your fuel bowl, it's not a bowl but a chamber wich chainges volume while fuel is runing away threw the paseges into your air flow into engine, as this happens the other side of the diaphram is pushing on the fuel becaus it is vented to the outside atmosphier, now this is how the balence is done wich equelizes the psi and volume of fuel in the chaimber and outside atmosphier to keep chaimber full, enoph fuel and needle cloases, reduced volume in the chaimber begins to open needle valve, hi use opens it more, ect..
atmosphirec psi wins out over fuel psi.
at least it is saposed to, make shure outside air gets to outer chaimber and make shur the needle is clean and new and has good spring and seat and find instructions on adjusting opening lever if apliclable for proper fuel leval,
a stuck, worn,dirty needle will flood engine,
misadgusted lever will also.
hope this helps |
