I've had a 1998 Honda foreman 400 for about six or seven years. I recently put a warn winch on it, and got a warn plow for winter use. It worked several times really well, but the last four or five attempts to plow, the atv stalls out and is hard to get going again. It has gotten to the point where it stalls after about two minutes. It won't start again for several minutes, but does crank for awhile. But if I let it sit ten minutes, it fires right up, then dies again.
Im wondering if adding the winch and plow is too much for the battery. The stator is working fine, charging around 14-15 volts. When I crank it when it won't start, the voltage drops to around 8-8.5 volts. But, it seems like once I get it started, it should continue to run on the stator, like a car alternator? Does it need a solid battery to keep running after its started?
My ear tells me maybe a fuel problem. But I also have never replaced the battery in all the years I've owned it. If I need to pull the carburetor and rebuild, it sure would be nice to start there instead of an expensive battery. Or maybe a choke/flooding issue.
Im thinking possible problems to be:
fuel screen in gas tank
anything else I might be missing (other than compression, but lets not go there yet)
thanks in advance
