Fluggie: Kind of figured I'd get some fur flying on this one. Don't get me wrong, I'm not against covering exhaust stacks. If your going to do it, do it right. I only ever had water down a stack twice that caused any problems. First time was Farmall 300 and it did have a soup can over the mufler. The exhaust pipe was loose in manifold thus allowing water running down mufler and along the hood to fill one cylinder full. Removed that plug turned it over a few times, put the plug back and she fired right up. Second time was Farmall 560 diesel with a bent rain cap, that actually deflected water in the mufler. My contention is this, if you got water enough to fill a cylinder tractor was parked beside a tree, building or some other object higher than the tractor and that object caused a downdraft, and deflected rain water down the stack. That or you have or had leaks in the exhaust system. If the tractor is parked in a open area, a 10" rainfall in 2 hours will not fill the engine with water. Air currents over an open upright pipe will allow only a very small percentage of the water down the stack. Remember all the tower silos with no roof. Very little rain or snow ever got in the silo due to air currents over the silo. Put a rain gauge in one of those silos, it will register a minor fraction of the rain gauge in your yard. Yes Allan my last 4 tractors and combine all came with those contraption you call a rain cap. Most of them went in the scrap pile within a year. Same with those dindy little things IH called tool boxes. I put a tool box on a tractor that would hold something, and my soup can was one of the items. You guys just don't take time to stable your horse for the night. Remember the old gray mare, you brushed her and put a rug on her. Surely you can take a few min. to put a soup can on the mufler. One other thing, if Farmall M didn't start after the rain I'll bet the real problem was wet distributor or cracked cap.
