how did you make out?

I've had a similar experience with my friends tractor.It did what yours is doing and has all the same problems. 6v changed to 12v did all the things mentioned above and it still acted the same.Now this is what I finally did that cured his.It was a fuel problem.Blew out the lines,and cleaned out the bowl many times but still would have the same problem.What I finally did was remove the sediment bowl,and remove the part that screws into the bottom of the gas tank.Once you take that out you'll see what I,am talking about.There's two short stems sticking up plus a fine screen on the end as well .As you can imagine it rusts up over years and gets plugged with crap from age so I cut all that stuff off and of course you should have a inline gas filter installed on your fuel line somewhere before the carb.After doing that it runs fine and hasn't let him down yet.Oh yeah this took several years to get it running for him as he;s not mechanically inclinded and it wasn't like I saw him everyday.If it would have been my tractor and I had it in my yard it would have been figured out sooner.So give this a try and who knows.Larry

Thanks for all the suggestions, I've been busy with the holidays and all and haven't had a chance to work on it yet, but I plan to get a space heater here before spring sometime.... I will definitely try the key switch bypass first. As for the fuel bowl suggestion, I did take it off and cleaned it well, but the screen that is supposed to be on the stems is not there, looks like it was at one point but it must have come off somehow, maybe I replace the fuel bowl as well????

Ok, rewired the entire tractor with some heavy duty 12g wire and replaced the key switch. Ran well for about 15 minutes and then crapped out just like before. I did purchase a fuel/sediment bowl too but haven't installed it yet. I had a buddy look at it that works in an auto shop and he took the fuel line that goes from the bowl to the carb to shorten it because he said it was too long and was looping funny causing it to fight gravity. He seems to think it's fuel related or something is happening when the tractor heats up. Tested all electrical components and they are good. Could probably use a cap and some plug wires but I don't think that's the entire problem.

So, next weekend we will:
- drain gas tank
- replace fuel bowl
- hook up shortened fuel line
- replace cap and wires
- take off the fuel tank to check for leaks in the header

If anyone comes up with something in the meantime, let me hear it. Thanks!

Have you tried running it with the gas cap loose the vent might be plugged.

Know any body with a boat tank?
Use it to bypass every thing to the carb.
Even a siphon out of a gas can would work after siphon is started

Thanks guys. We did take the gas cap off because when we opened it it did let out a pretty good pressurized hiss, but no luck. It could probably use replacing anyway as the rubber seal is cracked.

If by boat tank you just mean a portable gas container with a pump ball than yes our pontoon has one. So, you would just do this to see if it's related to the fuel bowl or gas tank? Just run a rubber hose directly into the carb from the boat tank or something?

Yep set the tank on top of the hood hook the hose to the carb fuel inlet pump bulb a a dozen times or so to get flow started and try and start it.

Went to try this and now I got not spark at the plugs, got it at the wire coming off the coil but the plugs have not spark. Bypassed the resistor to see if it helped and got a little spark but not much. Could this be wires, cap and rotor? This thing is drving me nuts!!!
