a friend of mine has a MD and it takes about a half hour to get it started on gas. when he gets it going it runs fine, switches over to diesel fine and then he shuts it down, then it takes forever to start again. do you have to switch it back to gas before shutting down? if you do how? i know this was dicussed before a couple of weeks ago but i can't find the discussion. thanks

Haas has given you a lot of good information. I just want to second what he said about the choke. Since there is no adjustment on the carb, the choke makes all the difference while running on gas. You need to find the choke setting where your engine wants to run. I start on full choke while cranking and then back off to 3/4 choke when it starts. I can back off to about 1/2 choke as it warms, but anything less and it runs rough.

i took my friend to seriously, it doesn't exactly take a half hour. it does take some fiddling though. you probably have to crank 3-4 good times brfore it starts.

sorry, thanks

its best to shut down on gas ,helps clean out diesel for next start and cool down engine ,simply pull down throttle as well as lever for gas at same time

Well, if it is cold, say below freezing, I don't think that would be abnormal. If it's doing that in warm weather, then maybe some carburetor adjustment is needed. Not much you can do to the carb though without taking it off and disassembling it.

Procedure calls for switching back to gas side for shutdown, then shutting off the gas to the carb and running all the gas out. After doing this be sure to switch back to diesel so the decompression valves will be on their seats to cool. If not on the diesel side after shutdown, the valves can warp. However, if it takes 30 minutes of fiddling to get it going, I doubt that the shutdown procedure is your problem on starting. I grew up on one of these things, and we never switched to gas for shut down. We always just pushed the throttle lever down to shut off and left it. Never had much trouble starting it. So...I expect you have some problem with the starting set up. You need to check that all is working as designed on the switch over system. Do you have a good ignition spark and is the switch located in the front of the manifold still connected and working correctly. The chamber in the front of the manifold is where the ignition switch is located to ground the magneto and shut off the spark, That swithc is operated by the switch over lever. The switchover lever also works butterflys in the manifold to direct air through the carb on the gas side. Also, works the float in the carb so that it is raised up on the diesel side to stop gas flow. Check that you are getting gas flow on the gas side by opening the petcock on the carb with lever in gas position. And finally, check the operation of the decompression valves which are also operated by the switch over lever. There is a clearance setting for these and they may not be opening enough. YOu have to remove the valve cover to set this valve clearance. I find in starting my MD, that it takes full choke for it to start even in warm weather and then gradually decreasing choke as it warms. Usually starts on about the third crank, even after sitting for quite a while.
