Guys,
I need some help. I have a customer with the Nissan K21L engine and above a certain RPM it begins to "surge" just like a velocity governor out of adjustment. I checked for air leaks at the carburator, drilled the rivets on the side of the electronic govenor and inspected, and played with the speed pot adjustment with no help. Still the up/ down on RPM's at the higher speeds. Any ideas??
