If you use one of those spark plug sockets where the top looks like a nut, then put a box end wrench on it you will have plenty of room. Are you changing plugs because it has become hard to start on gas? Many people have done this only to find it doesn't help....it is usually followed by a new coil, points, cap, wires, and a carb rebuild and then after all this has been done....she still don't like starting on gas. The problem I have found many times is that the 2 flippers in the intake manifold aren't closing 100%. And believe you me, if they don't close 100%, the air will not flow through the carb thus not pulling up the gas. The air will always take the least path of resistance. The only way to check this is to pull the intake, close the flippers, and snake a flexible light down the air side of the intake. First one port, then the other. If you see ANY light on the engine side, you have a leak. Open the flipper and send a dremel tool down there and clean out the crud where the flipper is supposed to seat. This is the #1 problem with dual fuel engines not wanting to start on gas. I have bought so many of these tractors for next to nothing, spent one afternoon doing the procedure described above, and resold the tractor as a smoooooooth starter. Hope this helps. Drew
