90 percent of all carb issues are ignition 120-130

It's been a while since I last visited or posted, sorry!

I was reminded of this adage since I had to park the 122s due to a hesitation problem (and winter with no driver's side window!). It has a B20 from an 1800 in it.

The symptoms:
- Would idle fine.
- Revved up fine in driveway.
- Ran well in 1st and 2nd to end of street.
- Would hit a wall when accelerating right upon selecting third gear. Felt and sounded like fuel starvation of the first order.
- Could then "limp" home by lugging engine.
- Would idle and rev fine in driveway again.

I "pushed" it one day to see if it would clear out and it got a tiny bit better. I could coax it up to 50mph in 4th.

While considering options, I had three things in mind:
1) I am already suspicious of the fuel pump and there could easily be a bit of junk in the fuel tank obstructing the pickup.
2) My stepson's father (a pretty good mechanic) put a junkyard Mallory Unilite in it.
3) The title adage.

After removing the "mechanic's" before pump fuel filter I tried it again but it made no difference.

So I order a new pump from IPD.

Before I get around to installing the pump, I send off a box full of distributors to Jeff Schlemmer (advanceddistributors.com) for rebuilding and recurving. $150 later I get back the dizzy and a note that it was a real bear to work on (It's an early dizzy VJU 4 BL 33). He set it up for ported vacuum instead of manifold vacuum.

I install it and ... nothing.

Oddly, it would static time and then "cough" and nothing. Attempting to recheck timing I got no power. I touched the points lead (at the bolt passing to the exterior of the carb body) and poser would return... Odd. After a few attempts at this I gave up and ordered new points and condenser from IPD.

New stuff arrives and in the meantime Jeff is puzzled 'cause it ran beautifully on his Sunnen. (!?!?)

So I install the new points and condenser. Hmmm. What's this? The terminal at the bolt has long "ears" on it and when the terminal is pushed all the way "down" they come REALLY close to the base-plate... Ah, HAH! Apparently they were very very close before and the ignition circuit was arcing and grounding out. Hence my "touching" the lead with a screwdriver would break the arced connection and I would have continuity again!

Whew!

Sure enough, put it in and it works. Very well I might add.

And yup, the "fuel starvation" problem is gone too!

I highly recommend Jeff (even though I had this issue) for your dizzy needs!

Just thought you'd like to know.
