My plus4c team is after 3 gallons and my runtime is 5-7 minutes with 6,5mm venturi. My pipe is 9901ss and 41021 header. Os p4 plug. Temp about 240*. it isn't over.. I don't have power on top. with that temp. and 6,5 venturi. Engine has still compression.
Has somebody the same problem than me ? I don't know what can I do with it

Are you sure your end points are set correctly? Should be getting better economy than 5 minutes. Running for breakin? Sounds like you may have the needles set way out of whack. I would try starting over with needle settings back to factory.
