D4 pony Governor oil???

my governor on the pony engine is getting stiff. i want to add some oil to it and see if it will free up. can i take just one screw out from the cover and add oil through the hole?

found this with google:eek2:

ok i oiled my pony governor today. i accomplished this by drilling a 1/8 inch hole in the back cover and using a hypodermic needle and syringe to fill the rear housing. oil transferred through to the front because a drip developed behind the governor pulley. anyway it is working as it should now.

oh i used a small screw to plug the hole so now if it needs it again i can just unscrew the plug and re oil. i used ATF

also need to add that this is the new style pony governor on a D4 6U. on the old style you can remove a cover screw from the pulley and oil through the screw hole and replace the screw.
