[DMCForum] Re: New business



Yes, I'm still running the old ignition stuff. I know it's not great 
but I'm pretty sure that's not the problem.

Converter isn't stopped up. I have pretty free flowing exhaust. The 
cat doesn't glow.

I've been double checking the timing every time I make a change to 
anything.

-BUT- you did give me the bright idea of disabling the advance when I 
check it. Good idea. I'll do that.

I have read my Hayne's fuel injection manual. It's very interesting. 
The most common, repeated listing for my problems (which happen to 
include hard cold starting) are "CO basic setting incorrect" 
and "control pressure regulator set too high/too low".

I've already proven the CO setting was wrong because I got more power 
as I adjusted things. The cold start valve works perfectly. I tested 
it. I'm suspecting the CPR even though it's new. Can you adjust 
control pressure on that thing?

Dave S. offered to let me borrow his fuel pressure rig. I think I'll 
take him up on that.
