RE: Surging Moki 180 with perry pump
Folks,
There were some issues with the Perry VP30 pumps ... some were generating air bubbles in the line to the carby. I had one of those faulty units and Gary Conley (the manufacturer of Perry pumps) suggested I return the pump to my LHS where it was replaced. Apparently Conley engineering now has an improved testing procedure to ensure this type of fault does not occur in newer units - Good work Gary Conley!!
