The 790 Bonnie needles are actually marked NAGB; I installed them today & retested.

The 4 - 6k RPM range @ WOT is heading in the right direction & is now in good shape, but the 4k 2nd gear cruise went from approx. 14 A/F to 16+ A/F; & warm idle (no choke) is still in the 12 A/F range.

So...I pulled the NAGB's & installed (2) .47 shims on each & will retest again tomorrow. I figure its a 50/50 shot whether 1 or 2 shims will be better, so I went large to start.

If the 4k 2nd gear flat road cruise goes well & the 4k - 6k WOT is still good then the pilot screws will be the next focus.

Stay tuned
