John,
When I first tried to fire up my 20B I had lots of trouble.  The plugs would
foul (excess fuel) and then nothing.  When this occurred, they wouldn't clear
with additional cranking.  If I removed the plugs, sprayed them with carb
cleaner, blew them off and reinstalled them, I could get it to fire.  The coil
fuses would blow when first starting to crank the engine.  Larger fuse was
required and they haven't blown since (amps drop way down once initial cranking
in past).  Tracy has mentioned that the coils can draw larger current when first
cranking, so this seemed logical.  Now that I have my starting technique
refined, and a few other glitches corrected, it starts the same each and every
time.

My COLD starting technique is as follows (our mileage may vary)...
EC-2 A-B Switch - A
Coils - ON
Injectors - ON
Cold Start - ON
Mixture - RICH
Throttle - CRACKED SLIGHTLY
Main Fuel Pump - ON
Main Battery Contactor (Powers Up the EC-2 & EM-2) - ON
Engage Starter

As soon as engine fires I start leaning using the EC-2 Mixture adjustment knob.
After 30 secs or so, I simultaneously switch off Cold Start and go full rich
with mixture knob.  I then start leaning again with mixutre knob, maintaining
smoothness.

Hope this helps,
Mark S.
  




Hope this helps.
