I am looking for your suggestions on a problem on my 841 gas. Last winter I rewired the tractor, pulled the tank and had it rotted out and lined because of rust, rebuilt the carb, installed electronic ignition, new coil, cap, rotor and 216 plugs. Ran pretty good afterwards. Since winter I have only used the tractor about 10 hours and it is now fouling plugs, black soot, too rich. I put new 437 plugs in it tonight and it runs good again. I have read the manuals on carb adjustments and I am trying to keep it on the lean side. The air cleaner is clean and I can not find any vacuum leaks. The tractor just doesn't seem to perform well under load even though it runs well sitting still. Has anyone come up with a better procedure for carb adjustments? What are you running for timing? I am currently a 4 degrees at 600 rpm, around 10 degrees at 1200 rpm. Thanks

went through that with my 871 gas not long ago. You can try 437's but I suspect that the fouling cause is still not identified.

Drain the tank and put fresh gas in. Check your float, and blow out the carb and jets and make sure float is not sticking.

I suspect you have a timing problem more than a carb issue.

I ended up replacing my timing gears because they were so worn that there was slapping on the worn gear teeth and I could not keep it timed and the plugs kept getting black soot. Wether I used 437's or 216's. That fixed it and quited down the knock to a non-existant knock.

Try gapping the 437's at .030. and the 216's if used at .025.

Does it foul plugs after you have been running it for awhile, or does it shut down ok and foul when you crank it back up? Is the tank shut-off staying open and the needle and seat leaking which would cause the carb to fill with fuel after you shut it off? After it has been shut off for a day, loosen the carb inlet hose and see if fuel runs out. If not, it's something else.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and ... [Read Article]
