801 carb problems?

Anyway, I start mowing and everything is great and then 15 minutes or so into the mowing, the engine startes to die. I can work the throttle (up and down) and or apply choke and keep the enine running but I usually cannot keep mowing. The engine surges up and down when I start to mow again or drive for that matter. Sometime I can shut down for a few minutes and cut.

Anyway, I cleaned out the carb and reassembled but the same thing keeps happening.

The governor seems to be working. At least until the problem startes.

Any Ideas? Thanks for the help .. Bill

There is really no good way to check an intermittent coil problem like this. The resistance tests really don't show anything until the coil burns out. The best way to catch them that I have seen is with an electrical tach connected to the coil. A jumping tach = coil going bad. Doesn't help on a tractor with mechanical proofmeter but it is a good diagnostic tool.

Good Luck!

I also cleaned out the oil from the airfilter. It was overfull and looked like some water had accumumlated in it. I refilled to the proper level and reassembled.

The first time I attempted to clean out the carb, it looked ok on the inside but I did have to take it apart again. It flooded and fuel escaped through the carb over flow. It seemed ok the second time after I adjusted the carb float. It has a Zenith, instead of the original M/S carb.

Is there a way to check the coil without just replacing it?

It runs and cuts great until the problem occurs. No sign of problems until it happens.

Thanks again

Similar problem but I was able keep it going by adjusting the main jet. Mine seems to be getting too much gas (float issue?) Seems that partially closing the fuel shut off helps a bit also.

Thanks
