rhino carb leak
Morning all,
Rhino 250, when i open the fuel petcock with the unit NOT running, the fuel comes out the black hose from the bottom of the carb bowl to no end, the drain screw on it is closed as well. Safe to assume its a stuck float? Good whack with a hammer to loosen? or any other safer thoughts. Thanks |

ya, but of course, ugh such junk.
Thanks for confirming., wouldn't mind but i only use ethanol free from pristine tanks then thru a fuel spout mesh filter. I'm getting to the point of maintenance overcoming usage. Time for a huge upgrade.. Thanks again. |

Sounds like the float needle is stuck open.... sometimes the actual float will get full of gas to and not be able to float. A hammer might not do it.
Check your oil so that no fuel got into the cylinder, past the rings, and into the crankcase... if the oil smells like gas change it. You can check the sight glass too... if its level is higher then normal you most likely have gas in your oil now. |

An aftermarket carb is just as likely to get clogged as the original. You can slot the screws with a Dremel tool to remove the bowl.

Im removing the carb and will cut slots to open the carb, I was just pissed of the constant motion of repairs, I also checked the oil level and its the same so apparently nothing in the oil.
Thanks all, I'll give an update. |

I just noticed on my Bull 200,fuel hose from petcock to carb is starting to seap,wet looking around the clamp on petcock.I reckon I'm going to start replacing fuel lines along with some quality clamps.I ordered some 3/16" clear fuel line.Haven't found any quality clamps yet.

I'm hoping the carb is easier to get to on the Rhino than the carb on the Bull,just getting the air filter hose back on was a job.

I'll let you know after tonight, I'll be pulling the carb, but replacing with cone filter and hopefully corrected carb.

Lastly,
So the carb was removed, and i tried to dremEL out the set screws like everyone does, but my screws were broken off below the casting and even with a dremel it was tough to get into the screw to try and get a screwdriver in the new slot i made, alas,, no luck, so i used choke cleaner and could hear the float moving around, i reinstalled the throttle cable and choke cable exactly, but still a fuel overflow, so i'LL BUY A new carb, but,,when i tried starting it i noticed the thumb throttle had zero tension on it, and the engine was raving crazy. when i reinstalled the throttle on the carb there was a needle valve that went right into the hole in the carb and the plastic sleeve and spring just screwed right in w/o issue long with it.. and when removed and pushing the throttle the needle valve did move. Did i install something wrong with the throttle going into the carb to make the carb rev to max when i start it now? or is the real issue still in the carb, with a new one on its way anyhow. thoughts? ps-when it starts and revs to max the only way to slow it is throw the choke lever to the opposite direction, and the throttle level does nothing..? ugh... |

found the issue.
when you pull the throttle from the top of the carb, it unscrews with a spring, needle valve and plastic insert. Well the plastic piece needs to have the notch or cutout face the air intake tube. Problem solved.. |

Real F-4040-A Tygon fuel hose isn't cheap,$1 to $2 a foot for 3/16",which 3 foot would probably do the whole atv.I'm going with better clamps to start out before replacing fuel lines,even though I know the fuel lines will probably need replacing also.
