governor question

Postby areger23 » Thu Feb 15, 2018 5:48 pm

my 1950 cub doesnt seem to activate the governor unless you are above 3/4 throttle, it likes to bog when letting the clutch out in 2nd and 3rd gear. the engine is freshly rebuilt maybe has 6hrs on it. not sure if the governor isnt set right or its a weak governor spring, any suggestions would be help full

Spring will help. The screw on the front may be turned too far out too. The carburetor linkage could be slightly out of adjustment as well. I had governor issues and all 3 were my problems.

I am having similar issues with my cub. I have nothing from idle to half throttle. Tractor runs great but there seems to be no response in half of the throttle. Thinking of taking the governor off. Are there any surprises I should be prepared for

If the governor responds at higher rpms, then before you remove anything, check the linkages for play, slop in movement, adjust the throttle linkage per the manual and replace the governor spring.

By responding, if you mean the governor will not allow the engine but revs so high, then yes the governor works at high RPMs. The throttle linkage moves the entire time except for the linkage that comes out of the governor to the carburetor. I have no movement of that linkage until half throttle

I mean responding as when a load is placed on the tractor, the governor increases the throttle to the carb automatically to keep the tractor from stalling.

Most of the time, the problem you are having in no movement (or delayed movement) is from slop in the linkages, an out of adjustment carb linkage, and a weak governor spring.

I understand now. Yes it works at full throttle. The spring outside the governor that links together both rods is very sloppy. Hole is elongated I am sure. Just didn't think this could be the entire problem. Seemed like something on the inside, but I am unfamilar with this governor stuff

Brodalick , the governor insides are very reliable and almost never the issue.

1) look to see if the level that the spring is on is not cracked or bent in some way
2) If you have no response for 1/2 of the throttle movement go to the manual and follow the linkage adjustments.
3) If after that you still have issues replace the external and internal springs per the manual
After the above then consider removing the governor. do you have a mag or battery ignition?
When you only have 9 horsepower you need to know the names of all of the ponies!

Battery ignition. Tractor idles great and I assume full throttle is working correct cause top speed is alittle over
6 mph.
