Taking apart the governor

Hi Guys,
Got some feedback that moisture in my governor might be causing my 51 H to rev up to high RPM during a cold start (it did it again). I was lookin at it this weekend and have some questions: There is a pipe that comes off the left side of the carb into a gizmo that has a cap on top w / 2 screws and a piece of tubing coming out of it's top and running up into the front of the block. It sets on another gizmo with about 8 bolts going around a D shaped plate, which one is the governor? Second question, do I need to pick up a gasket before I pull it apart? Is it possible there is something worn out in there, even though it works fine once it warms up? Third question, can I open it up and spay some WD40 in there, and would that help my problem?

Thanks Guff

Let's see if I have this right. You don't know where it is, you don't know what it is, you don't know how it works, but you are going to 'fix it' by spraying it with WD-40? First, get a service manual. Second, WD-40 is 90 percent fish oil, was developed as a water displacement (WD) or in other words, a spray to protect steel from water (rusting). It does work great to clean the top of a gas stove! GordoSD

Condensation freezing is a common problem with M govenors. When ear corn pickers ,the old 2M's were mounted on M's We always drilled a small hole in the tube to let cond drain out. Never had problems again

Which tube do I drill a hole in, the tube that comes out the left side of the carb or the tube that goes up into the front of the block? Which one of those is the governor, the small deal with two screws or the the big one with 8 or so 7/16 bolts?

Do you leave the throttle at low[minimum] when the engine is shut down? Try leaving the throttle lever at its lowest [idle] position when you shut the engine off for the night & then opening it up again when you start it in the morning. Also try using a hair dryer pointed into the governor housing to dry things out while you have the cover off.

The WD-40 will definately clean up the insides of the gov. Go for it. Just be forewarned that getting it all cleaned up may reveal some other problems that need to be dealt with, so you may want to wait until the tractor can be down for awhile. I kinda like the heat lamp idea. Even though it is not a permanent solution, it will buy you some time.
I also do not like the idea of a cold engine running wide open right after start-up.

I'd definitely want to have some gasket material on hand before opening anything up, so you can at least cut your own replacement. OE gasket even better.

I personally hold WD40 in low regard. It is a cleaner in my opinion, and might lubricate for an hour or two until it evaporates.

Mine has done that a time or two also.... I have discovered that there is some moisture/condensation that has frozen and siezed up the governor linkage... So when the motor warms up it works ok. But unless you are using it really hard and get it really warm it will not drive out the moisture and when it cools down again it freezes again. I have stopped it from happening right now by using a heat lamp to warm up the governor before I start the tractor. I will pull it apart when the snow gets gone and I can stand to have the SM down for a bit, But right now i have been clearing my drive and around the barns nearly every other day... The snow is pretty deep here and more is on the way. Tallperson
