Jeff,
After reading the suggestions today, I think that my engine is going to lose
its eyebrows... :>)

Glad to hear you got things sorted out and there really is no problem; so it
turned out that 1400 rpm was just too low to swap injectors. I think we all
learned from this discussion. I balked at buying the BR10EIX plugs because
they didn't fit. I like the suggestion of enlarging the eye brows to
overcome the problem ... will likely do that when it comes time to buy my
next set.

Steve,
Bobby Hughes suggested that I only test the disable switches at 3000 rpm or
above. So yesterday I tried that. The secondary acted the same, slightly
richer. The primary caused the engine to cough and choke up a couple of
hairballs, go really lean, then come back and run slightly richer just like
the secondary. They both came to a mixture of 11.6-11.7 after the disable.
This works the same on both A and B controllers. I think this means that
the EC-2 is working, although it is taking a while to get the decision made
to turn on the secondary after it realizes that I have turned the primary
off. This time delay was causing the engine to stop when I ran the test at
idle. The way it acts might be a little disconcerting to a passenger if I
tell them I am checking to make sure the engine runs ok....:>)
On another note, I took your advice and bought and installed the BR10EIX
plugs yesterday after the test. I found an old plug wrench and ground it
down in order to get them installed. Naturally the wrench was so thin that
it cracked on the install. I doubt that it will hold up to do a change. I
plan to get a wrench and have someone turn it down to fit.
I assume that you have already done this. What dimension did you turn the
socket to? It seems that the opening in the block is one inch but the
wrench would need some clearance? I am way too tight to buy that wrench
from Racing Beat for $82 + shipping! :>)
