Jeff---Others have indicated that the problem is either the (hole in the) carb diaphragm(s) or the ignition timing. I would agree that it is most likely one of these.
As you may know, pumping the gas pedal doesn't squirt any gas into the engine with the Stromberg carburetors. What pumping the pedal does do is interrrupt the vacuum pull on the line that goes to the retard unit on the distributor. This could be why there's a momentary reprieve to keep the engine alive, as the timing trys to advance. So it's my opinion that the engine is trying to run while the timing is extremely retarded. I would check things related to the point gap, and the bolts that hold the distributor from moving about. Write back, if you need some ideas here.

Hello all, I have an issue with my '73 TR6 and am looking for some
experienced thoughts. My TR is garage kept and not a daily driver, so she
gets started/ran about once a month or so. since my last start however the
car now has a power problem. The car will start with the choke out and
pumping the gas pedal but even once she gets to operating temperature she
won't stay running if I ease the choke in. If I am running down the road she
has incredibly slow pickup and the top end has come down to about 40mph at
2500rpm in 4th gear. When I get to a light and have to slow down the engine
dies almost immediately unless I pump the gas pedal, or pull the choke out,
it holds a steady fast idle warm with the choke all the way out. Starting
from stop I have to put the gas pedal all the way to the floor and wait as
the engine very slowly builds power. In motion 3500rpm is about the max I
can get but sitting at the light pulsing the gas pedal I can get 5000 to
5500 rpm, but again if I stop pulsing the gas and the choke isn't out she
drops to 0 and dies. There is no funny colored smoke, no backfiring, no
cylinder misfires or no fires, as far as I can tell, it feels like it is
fuel system. The carbs are the stock duel strombergs and they were synch'd
by a mechanics shop about a year ago. Up until this recent fireup she has
been running well so I don't think it's a major issue but. Inline fuel
filter is new and the fuel pump seems to pump a good stream of fuel so.
before I start screwing with the carbs I'm wondering what your thoughts are?
What sequence of things should I go through before taking the carbs apart
etc and screwing up a good sync? I appreciate the help. Thanks.
