To all, Thanks.
Yes it is the 3A. Sorry I should have been more specific.
I have one of Joe Alexander's heat shields, but also have a header on this
car.
It has a 270 degree modified cam from BPNW
Pulling out the choke makes it worse.
Today I "fluttered" the gas pedal and increased RPMs and it cleared up but
returned soon after I drove with a steady position on the pedal. This tells
me that it is being fed too much fuel (?), and to be honest, behaves like it
is only one carb.
When I shut off the car the temp gauge goes a little north of the mark
between 185 and 230.
The thermo bypass hose was plugged when I disassembled the motor but I did
not replug in when I reassembled.
I drove this car about 35 minutes to breakfast with my Sunday LBC chums and
35 minutes back hitting speeds near 80 MPH (OD) and the car ran like a champ.
I pulled into the garage, went into the house to get something and about 5
minutes later started her again and drove off. It started missing about two
minutes after that. That describes the experience 2 or 3 times in the past.
I had a similar experience once with my 6 and it was because there were
Grosse float valves with the little ball. I replaced then with OEM style and
it
went away. It does not appear that these carbs have Grosse, although I have
not removed them to look at them. They appear to be the ones with the rubber
pointed tip, but only by what I can tell by looking at the end I can see.
Jeff Palya rebuilt and polished them for me.
There is not something basically wrong here, as this car runs very strong.
Something is changing, and I am believing it is caused by heat. Of course,
90% of carb problems are electrical!
