Re: stops running
I hope we're not chasing a fuel issue when it's a bad coil. When it dies, pull the plug, check for fuel at that point. The plug should appear wet. Check for spark immediately after it dies. No fire= bad coil. Lean plug with fire= crank seal?
I am at a loss here. The tank doesn't have any trash that could plug the pickup? How can we check crank seals? They could work as a one way valve, allowing air in and no oil out? O2 molecules are way smaller than oil molecules? What else? |

Re: stops running
hello so what you are saying is if it is a crank seal leaking there may not be a oil leak?
i will have him check for spark also and the tank is clean |

Re: stops running
Another thing to look at is the fuel filter. Those carts have a very small filter on them usually. They can get "chit" in the filter and still work but not work well.

Re: stops running
I'm not sure. You know how a seal is made, with the spring holding the lip on the inside??
If it became hard, (as they do over time) it would expand when hot, allowing for an air leak. The air molecules would go through, but the oil would remain inside. Theory could be right, but it is a theory. Let's check the plugs for now. I really don't know if the seal would do that. I know of some 2 cycles that leaked at the crank with no oily film, buy they do not have a sump full of oil either. In that case the plug reading would show lean due to the extra air. You knew that was it, because no other mods had been made to lean it out. Let's look at the plugs. Dad knows what a lean plug looks like? Whitish or very light grey to light brown.? I'm really guessing now. I'm not gonna BS anybody, it should be running. Let us know what happens. Especially if something fixes it. I HAVE TO know now. |

Re: stops running
That reminds me....The flow on the new fuel filter is the correct direction? Arrow towards the carb? That could cause a problem.

Re: stops running
I just had a muffler drive me nuts for three days. My cart lost power and I looked for everything under the sun to figure out what was happening. It would be running pretty good and suddenly die. I would start it up and it would run for a few minutes and die again. The power loss was dramatic though. It wouldn't go up a hill hardly at all. I took the muffler off and ran it this morning. If that thing had wings, I'd be in Hawaii by now!

Vapor lock can be caused by a poorly routed fuel line. Too close to a heat soource will cause vapor lock. The stock hoses are not close to a heat source. Another thing is if the insulator on the carb was removed it can vaporize fuel in the carb. That's the plastic piece between the carb and cylinder. Let us know what you try and what happens. |
