I know some use the EC-2’s Program Button to = prime the engine, pressing as many as 20 times before attempting to start the = engine.  I’m curious if this is something that’s always done, or only = when very cold.  How do you know how many times to hit the primer = button?  Trial and error?    

 

Here’s the technique I typically use for my 20B = with 550cc injectors (but haven’t tried it in really cold = weather): 

 

1)       = Turn On Main & Aux. Battery contactors, fuel pumps, EC-2, injectors and = coils,

2)       = turn “Cold Start” ON,

3)       = Turn mixture knob full rich,

4)       = Hit starter until engine fires,

5)       = Within 3-5 seconds, turn off “Cold Start” (leave mixture knob full = rich)

6)       = As engine warms, slowly bring mixture knob to 12 o’clock position.  =

 

This seems to give the most repeatable starts (for = me), and I’m afraid to tinker with success.  However, if there is = truly a better starting procedure, I’m open to = suggestions.
