Jerry, I appreciate your input, really! I think you're misreading my posts, though. I've done everything you suggested except swap out the power valve - which doesn't have much to do with low-speed, off-idle performance. I haven't touched the accelerator pump because I still don't have the parts to swap. I opened up the idle mix - suggested by two of you - for a partial improvement, and ran up the initial timing to no particular effect either way.
When I get the low-speed, off-idle, primaries issues sorted out I'll look at the secondaries, power valve and other top-end tuning. I'm waiting for parts on that end as well.
I'm also really limited on time - I have more time to sit here and yack about it than twiddle a screwdriver. It's frustrating.
