Hi Jon,
I hand start all my engines (welllll, not my car <VBG>

. Pumped engines I open the throttle and choke until fuel reaches the carb. Flip the prop 2 or 3 more times (depends on the engine). Shut the throttle to idle, connect the glo-plug heater and flip the prop. The engine should start in just a few flips at most. It is very easy to flood the pumped engines, especially using an electric starter.
Happy flying,
Will
