Ken, I have a RevMaster 2100D with the RevFlow injector/ carb. Mine runs great warm or cold.
All my fuel lines and fittings are 3/8 inch and standard gravity feed from the header tank. I turn the tank fuel valve off to kill the engine. Here's what I do to start; Mixture off, throttle closed, tank fuel valve on, drain gascolator. Mixture full rich, throttle cracked open 1 / 4, wait 3 seconds, and hit the starter. Usually after 3 blades, it fires. I immediately set the throttle for 1000 rpm and lean for best warm-up idle while watching the oil pressure build. I've watched the fuel flow at my carb. It takes about 3 seconds from when I push the mixture to full rich before the fuel to start to flow. Rather than run the starter for this duration with a "dry carb" I just wait 3 seconds. Good luck, I hope this helps. John Bouyea KR2 - hanging the engine accessories KR2S - boat hanging from the rafters john_0...@bouyea.net www.bouyea.net
