John,
I made a tool to set the jets at a certain depth by grounding a 3/8 inch bolt
(2 1/2" long) flat as I could get it and then double nutting the bolt to the
depth I wanted to set the jet. I checked it at various stages of beating the
jet downward...it takes some serious and well placed blows..with a digital
caliper with a depth probe. If you go too far you can drive the jet back the
other way with a bronze valve guide for a Honda (got mine from Apple
Hydraulics so call them for details) that fits right over the bottom of the
jet so you can pound it without destroying it. I also used some of AH's lean
B1A needles to overcome a running rich problem at 5280 ft.. A fuel pressure
regulator made a big difference too.

Thanks for all the comments. I am so sick of working the electrical
side, I decided to work on the carbs.
I topped up the dashpots with 90wt oil (which is recommended by John
Twist the MGB guru). I noticed some improvement there. I think I
will try the B1E needles again - these give about a 10% increase in
flow. I did this before and didn't see any improvement, but then I
found several electrical issues that were no doubt contributing.
I did not change the jets when I did the carb rebuild, because they
did not come with the kit. John Curto recommends having the jets at
least .120 below the deck even as much as .160 below. Mine are .108.
How do I move these jets? Do I need some kind of fancy press?
Can I do it with a punch?
