B governor question

My 1949 B doesn't seem to idle down correctly - it seems to stay at the same engine speed with the throttle set at 1/2 (6 notches) or at idle (first notch). I know I need to check the idle screw on the carb, but since the magneto has been converted to battery ignition a few folks have suggested that I check out the governor internals to make sure they're not modified. Since I've never been in one of these governors before ....:

Will removing the front cover and replacing weights/pins do anything with the timing? I wouldn't expect it to as long as I leave the gear alone but it never hurts to ask.

How much oil will drain out if I remove the front cover? Will a paper towel or two handle it or do I need a decent quart container?

Would the thrust bearing or governor shaft bushing also need replacing? Would wear on them have any effect on the governor?

Thanks for your help. I hate to take something apart and have unexpected difficulties ....! (Just described working on old tractors, didn't I?!?)

Bryan, Dick is probally right. If you do go into the governor check the shaft (#5) for a grove. If enough of a grove it possibly could hang up and cause your problem.Just something to think about. Dale

Bryan, If I was a betting man I would bet that you don't have any thing wrong inside your governor. The first thing to get out of the way is to get the idle set on the carb. After you have that set the throttle rod with the set screw up by the stearing wheel. If you start to move the throttle liver forward and it starts to go to a high rpm after a couple of notches you will have to bend the governor cross over rod. #13 in you drawing. and readjust.

Bryan, I took the front cover off my governor to replace the gasket and no oil came out. Also, my governor has the same problem, I think I'm missing the #9 spring also. Sorry I couldn't be more help. But I'm new to this. TractorMike

Your governor looks just like my D14's. Mine had the same symptoms. I was missing spring #9. This small spring should pull the carb. linkage in the idle direction. With the hand throttle in the max. position, make sure RPM's are not running away. With no load, and full hand position, the carb. should only be cracked open. Now, watch the carb. linkage close while putting the tractor under a load (I have a nice hill to climb tnat's handy) When the load hits, you should see the carb. linkage move, opening carb. maintaing RPM. I think if the governor responds well to loads and everthing works freely, I would not take it apart. But if you must, about 6 paper towels should do. Be safe, Trent
