I have three tractors that have this I-H start on gas and switch to diesel. The choke is the only way you control the amount of air you let into the engine when starting. The way I start mine is, I have the choke all the way closed when I hit the starter. As soon as it fires I open it to about the half way point. After about 30 seconds I can open the choke all the way. The should no missing on the gas cycle. If the engine misses on the gas cycle then I think you need to check plugs, points, plug wires and maybe timing on the gas side. None of my tractors miss after I switch to diesel. I have a TD9, a 600 International and a 400 Farmall. I have never had a head problem. Just make sure that the radiator is clean inside and out and you keep it full of water. Any engine should not be turned off right after working it hard. I always let them run for 5 minutes or so to cool. According to the owners manuel switching the engine back to gas for 10 to 15 seconds before turning it off is suppose to clear the combustion chambers of diesel fuel and aid in starting the next morning, but I could never tell any difference. One thing for sure though is that once you have shut down the engine make sure you put the lever back on the diesel cycle or you could warp the needle valves that seal off the gas pre combustion chambers. Those Diesel engine just sound better under load than the gas engines. A lot cheaper to run to.
