<DIV>Thanks for the info. I too am running a Greve. I've tried an Iron Bay regulator with a Cline one way valve after the IB vavel failed, am unsatisfied with the midrange, and am ready to go to the Perry pump. What is the length you are running on your Greve, from the glowplug, around the header, to the end of the main body of the pipe? What prop? I have no one around me running a similar setup, so I'm looking for a "cookbook" formula that works.</DIV>
