[6pack] Left hand turn stutter

[Andrew Packard]

Hello listers:
I completed the rebuild of my stock carb set up on Saturday
night, had a successful test drive that night, and then autocrossed
on Sunday.  I gave the car a "B" for overall performance since it drove 90
miles each way to get to the event and it was 100 degrees or so the entire
afternoon in California's central valley.  I have not yet rec'd my Stromberg
heat shield yet, so I ran without one.  I shared my car with a fellow club
member and we each took 5 runs each that lasted about 70 seconds each.  The
car did well the first two runs, but then began to hesitate around
hard left-hand corners for a couple runs and then was hesitating in only mild
corners.  I have an electric fuel pump putting out 6 psi that goes through a
regulator that reduces the flow to about 3 or 4 psi's.  My float height is
about 16.75mm.

When I first attached the stock carbs off my storage shelf
before renewing the gaskets, the car ran okay with them but gushed out fuel
when the car was off with the fuel pump operating.  During the rebuild, I
found the float height to be set too high at < 15mm.  When it all went back
together, the new float heights prevented excess fuel flow.  My inital thought
is to remove the regulator and allow for the full 6 psi's to reach the carbs,
keeping the fuel bowls full during fast runs.  I also thought about raising
the float height a little to 16.25mm to help maintain higher fuel levels.  My
other suspicion is that due to the heat from the weather, auto crossing and my
headers without a heat shield, perhaps I was boiling the gas in the float
bowls.   Could my timing also be contributing to a very hot engine bay?  I
don't have the specs on the timing off hand.

Any opinions and thoughts are
welcome.
