During priming I could tell the pumping action was starting to feel a little soft so I pulled the pump and sent it to Gary Terno. 530-477-7573
Gary overhauled it and sent it back in a week. $375.00 See below email.
Hey Kevin,
The wobble pump is a VERY early production model serial #0277 out of over 2500 made, but with that said it it in good condition but the o-rings were worn and brittle, that may have been causing some bypassing of fuel ? like I say could have, I did a update as to the fuel pick-up system at no charge and should help when going from inverted to normal flight.
Feel free to call if you have any questions.
Best Regards
Gary
I am very happy I sent it in for overhaul plus this should cure the engine stopping during the first inverted maneuver as in the past. Gary said the early pumps did not have the inverted tube mod so if there was a little air pocket at the top of the pump chamber it would suck air.
