Oil flooding distributor

I have a 44 M with a M & W 201PX live pump and a right angle Delco Remy distributor and have an odd problem.

Last winter while pushing snow I could not keep the tractor running- seemed like it was starving for gas so I spent a bunch of time checking the carb to no avail. Finally discovered the distributor was full of oil and fouling the points. I cleaned the distributor up and it ran fine.

I used the tractor in the spring to grade the driveway and had the same problem- much quicker diagnosis this time! Figured the seal on the distributor was failing so instead of using oil to lube the distributor I used grease hoping it would be thick enough not to work past the seal.

Tractor ran fine and used it a few times with no problems until yesterday- same problem!

It was not grease in the distributor so I am guessing it has to be hydraulic oil.

Anyone have any insight? Is this a seal problem or do I have a major leak inside the pump that is pushing pressurized oil past the seals? Are there parts available for the M & W pumps? I searched on-line with no luck.

Thanks,
Nate
 
Just remove the old seal and take it to NAPA or any parts store and they can get a new one. You dont need to keep pumping grease in there. That zerk should be removed and replaced with a plug. When the dist was new there was a slotted screw there so owner wouldnt keep adding grease. It was to be removed and a zerk installed one shot or grease then removed and screw put back in to remove temptation of adding grease. Only need one shot a yr.
 
If pump is worn and seal does not hold, a drip tube installed in adaptor housing will keep it out of distributor. That sounds like a will work, get by type repair, and it is , but, look at B model injection pumps on the 450 Diesel. IH used a drip tube on the pump due to a persistant small leak that the older pumps handled with a scavenger pump.
