Sounds like, to me.........There is a fuel delivery issue, starting with your fuel pump.......IF it is not operating correctly...the above mentioned "electric fuel" pump is the "FIRST" tip off.....If your stock fuel pump is operating correctly then the "electric" pump is unnecessary. Second as the previous post mentioned.....I would ALSO get my carburetor rebuilt by a competent re-builder.....CHARLIENY here on the FordBarn would be a good start (as well as your fuel pump). Then.....You have a good foundation to start from IF there is any more issue!!!!! JMO ........... IF you're having to pull the choke out 1/2 way then that "Says" you're sucking more air than fuel SO you have to balance that out by restricting air flow!!!! SO Where and why is the AIR to Fuel mix OFF???? Your sucking air from some where your not supposed to be getting it from!!!!! OR Fuel is not getting to where it needs to be in the correct volume SO reducing the air flow reduces the volume of air to fuel mix, increases the velocity of the air to help create more pull from the fuel side (hopefully) and it becomes more in balance!!! SO our carb also sound like it has issues!!!! PLUS sitting for long periods not being run helps neither component.




ALSO you may want to look back in the archives BUT with "electric fuel pumps" you "MAY" also look at what the PSI is the electric fuel pump pumping at.....IF memory serves me.....you should be around 3-4 psi from a stock pump and "MOST" electric pumps are 6-8 psi SO that could be an issue as well SO IF you plan on keeping the electric pump in your system then you may want to look at a pressure gauge and/or a pressure "regulator" as well!!!!
