I am by no means an expert on the MD or any other piece of equipment, but have had a little experience with one (it's still there on the farm but hasn't run in many years like all of the other tractors there). Don't pull or try to operate it on the gas side. It should/will start on the diesel side...this is how we started and ran it for the time that it was used. When my father stopped using it was because there wasn't anyone around to help him start it. There is a third valve in the cylinder head for each cylinder that is for compression release in order to run it on the gas side. This valve can/will be bent or ruined when trying to operate it on gasoline if the tractor is in operation/moving. This (according to the people that I consulted with when trying to get it to run right) was one of the reasons that there were as many problems with the MD. It's a great tractor to run with plenty of power and VERY fuel efficient, but takes a manual/books (was never able to get a hold of one other than the I&T Manuals that were very vague about it) and experienced assistance and patience in order to learn and run it correctly. The diesel injector pump looks a lot different than anything that I've ever seen. You may want to check / change the oil in the injector pump. Something you may want to try if/when you try pull starting it is to crack the lines at the injectors open and make sure that there fuel getting there. Leave them slightly loosened (engine should/will still start) until you get it runnig and then tighten them down. This way you should be able to ensure you get all of the air out of the system. You can tell if it's getting fuel because there will be kind of a white vapor coming out of the exhaust and that's when you will usually get it started shortly afterwords. If the injector pump is going bad it will most likely lose it's prime and be cavitated then will get air in the system and it will run like crap and usually just idle at best. If this is the case while trying to load it up there is a petcock valve on the injector pump that you can "bleed" the system with by cracking it open. If having to do so you most likely will be surprised on how much air will come out of it. We usually had to let it sit there idling and stuttering until it came back up. Most likely the govenor on it will not be good either. Just my tad bit worths of experience with one for all that it's worth to your tasking. Good Luck with it, I'm sure that if you have the patience and a few dollars that you will have an enjoyable experience with this tractor. My email is open and I am really interested in the outcome you have with this tractor and would like to hear how things work out with it. I still have over two years in the military left and little time or a place to have something like this to tinker with, but still would like to and hope to get the tractor and try to get it to running correctly some day. Hopefully it won't be stuck or stuck to bad by the time that day comes. Jim
