Governed Carburetors
« on: March 21, 2011, 06:51:49 am »
What makes a governed carb with screw in brass plug go bad?  It would flood saw out once warm even though set rich and no where near high range rpm.  Carb is WJ walbro on the partner 550.

Stuck a BB inside to plug of the governor jet  and all was fine. 

Any ideas way they go bad?

As I understand it some how that thing rattles around at a certain frequency dependent on RPM and richens the carb .

I had thought I had defeated the gov on a 2100 Husky but according to others who knew more than I evidently I had missed something in the process  by the way it ran . Not bad but not as good as is possible  for a stocker .Something else to do on the to do list which is getting rather long as time marchs on .

I have done a couple by inserting a "disc" of nylon & tightening the brass governor down onto it. The dia. of the disc must be "close to size" so the brass plug will squish it to fit nicely.
Also a drop of removeable thread locker on the brass plug.
Worked every time.

We found a trouble free way of fixing the carb governors. We changed carbs. Works every time.

As soon as I put the BB in this carb and no thread sealer was used. Problem was fixed. Heck on the 550 didnt have to remove carb to put BB in.  8)
