Oliver 77 throttle

56oliver · Jan 11, 2015

When ever I crack the throttle of my super 77 it surges for a couple seconds... Then it finds the right place on the throttle... Is this normal and is there any way to adjust it? The tractor is new to me and all I have is the ol put puts... Thanks

Try opening the main jet just a little. Surging is usually a sign of too lean, but it could just be the nature of the beast.

Common since there is no accelerator pump in these carbs like on a car. As Steve says open up the main jet a bit

IF adjusting the carburetor doesn't resolve the issue you may need to replace the thrust bearing in the governor.

There's a bumper spring in the governor that's supposed to take care of the surging. It's a bolt right in the front of the governor case behind the fan belt. Takes a 7/16ths wrench and has a lock nut on it.
