Tractor running rough...

Had a heck of a time getting my Ford 861 started last night after it had set outside (rain) for about a week. Finally got it started but really ran rough. Backfired under load a couple of times. I finally shut it down, not wanting to do any serious harm. Need to get some mowing done in the next few days though. Any thoughts where to start looking for a problem?

The distributor cap took some moisture inside, which could have resulted in some arcing and resulting carbon tracks which will result in misfiring and backfiring. Remove the cap and inspect closely, you may be able to wipe it out with a clean, dry cloth and all will be well again. If this doesn't work, replace the cap with a new one. While you are at it, wipe off the plug wires so that they are clean and dry also.

I go with Polish Mike and moisture in the distributor cap. Backfiring was probably tracking across cap. But could be water got in exhaust and now have a sticky valve.....
If it won't go, deternmine whether it is ignition or fuel. Do you have a sediment bowl on this fuel line? If so, check it for water.

Your points probably got a little corroded...File them & re- gap them. Check inside the distributor cap for moisture, also.

Well, yea. Sounds a lot like water in the fuel.
