I can't say I'm at wits end, that happened a couple of years ago. I've got an Oliver 1600 gas that keeps fouling the spark plug in number 6. I use it for a short time twice a day to feed round bales. A new plug will last from 3 to 12 days. They're just wet with gas, no sludge like oil fouling. I've tried drying them out with a torch, leaving them for weeks, they can't ever be re used. A new plug is all that ever fixes it.
My son thought it might be the carb flooding it out. We took it apart and put it in his ultrasound outfit on Friday about three weeks ago. The next day, I ground two loads of feed with it to work it hard. I fed round bales with it on Sunday. Monday morning,it started alright, but was missing before I even made it out the the tool shed. I've gone through 4 plugs since, usually just letting it miss for several days out of disgust and frustration.
When I change a plug and it's running right, it still seems to me that it has a slight swish when it's running. If one of the rockers was too tight on number 6, COULD that cause what's going on? I've been wracking my brain trying to figure out how. Maybe an exhaust valve sucking air on the intake stroke so the gas was just pouring in wet instead of vaporizing? When I run it a few days with a fouled plug, it'll be wet around the plug and will be running right down the side of the engine on the manifold side. I'm probably all wet myself on my rocker too tight theory, but I'm throwing things at the wall to see if anything sticks. With the loader in the way, it won't be overly simple to take the tappet cover off, and I don't want to risk ruining the gasket if there's no way in creation that it could be the problem.

Today's Featured Article - A Lifetime of David Brown Tractors - by Samuel Kennedy. I was born in 1950 and reared on my family�s 100 acre farm. It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
