everything is now running, but i have fluctuating revs. the throttle spindle can be moved slightly 12 o clock to 6 o clock, and
it will affect the idle revs from 900 to 2500
is there a bush or bearing within the top of the pump that can wear? i am about to give up and put my JX pump on this newer engine, only
because i know it works spot on.

the pump top has a brass guide in there and an o ring. they can and do wear.
