Tracy,

This brings up a topic that was thoroughly discussed in your absence this summer.  I think the consensus was that the primaries should be the same as the secondaries in case of a primary failure.  In the EC3 manual, you state that the primaries alone would be good for about 80% of full power.  I don’t recall you ever having a response to this thread.
I think I know what your opinion is, but would you like to comment?

Thanks,

Bryan

550cc is way more injector than you need so I'm not surprised it's running rich.  (why are so many doing this?)  Don't worry about what the steps in Mode 3 represent, just reduce it until you get what you need.  Of course the instructions tell you to adjust Mode 3 at a high throttle setting, not the low end you mentioned.  Mode 2 is for the low end (assuming you have the current version of software, see manual).  Adjust Mode 3 first,  test for possible need to adjust Mode 6 at staging point then do Mode 2.

Today the weather finally turned nice, the sun actually came out.  I installed the new injectors I received from fiveOmotorsports, they are 550 cc's.  With the mixture full rich, I hit the starter and the fuel really flowed in.  It finally started on the Weber at wide open throttle.  The plugs I'm using are the NGK - B9EGV, which has the electrode exposed like in typical plugs, unlike the center electrode buried in the hole, as in the normal plugs for the l3B.  These seem to stand some flooding better than the RE7C-L and RE9B-T 

With the mixture control full lean it ran, but with the program value knob I can't lean far enough in the lower rpm's, 1800 - 2000 rpm's and 13 #'s manifold pressure.  The manual says to go to mode 3 and lower the mixture in 3% steps.  Is this 3% step equal to what the mixture control knob achieves in turning it full left.  I guess I'm looking for some guidance here, so I don't get it screwed up and have to start over several times.  Thanks in advance.  JohnD
