I recently had the metering valve stick in the injection pump on my 1971 4020. I pulled the pump and had it rebuilt. While it was being rebuilt I asked if them to install the Stanadyne 29111 weight retainer to eliminate the flex ring that routinely fails.
I reinstalled the pump about a month ago but didn?t use the tractor until today. While using the tractor I noticed that throttle doesn?t seem to respond as quickly as it normally does on a 4020. When the throttle is pushed to the slow idle position the engine will idle down and nearly die, and sometimes will die just as I have seen this tractor do when the flex ring is failing.
My question is, should there be a significant difference in the governor operation with the 29111 weight retainer?
My knowledge of pumps is near nothing so I'm not sure my terminology is correct.
