hey guys!
so this case 446 i gotsed running last fall ran pretty darn good so says the owner. one problem he mentioned was the governer wasn't working. for snow blowing, he would just lightly push on the shaft for the throttle to add some speed when the engine started to work.
short of opening the engine (which i highly suspect i'll be doing anyway :smilewink: ) what else can i look for? there doesn't look to be any sort of adjustment for it and there isn't any force behind it while the engine is running. all the other engines i've adjusted had quite a bt of force on the governer shaft while it was running. springs are old but still in good shape. tried a few others with no change. just nothing from the governer. engine has all sort of power under load if you manualy hold the rpm's up where they should be.
it's this tractor:

the engine (and i'm going by my oh so fantastic memory) is a bf43(??) ....

If there is no force from the governor arm while running....time to pull the flywheel & timing cover. Either the governor control arm lever is broken off, or the governor is broken in another way. Could be the spider that separates the flyweight balls is shattered.

Yep, the only adjustment is via spring tension holes.
