Re: Advice needed for hard starting Dual AFBs and 745 lockdown



Evaporation is the real culprit. An electric fuel pump is the cure. Also it helps to keep the carbs cool. My wood spacers dropped my carb bowl temps from 180 to 110 !!!! Talk about an improvement. Don't use metal spacers. Something like wood or phenolic that will insulate.

Any info posted on how to install a "check-valve" into a fuel line?  Sounds like it might be a solution for the crappy gas problem...  Seems this is a problem most of us have.

you may also put a check valve in the fuel line.

Hi Mark,

I have a '63 Sport Fury 383 4bbl. It sits for extended periods (2-3 weeks) and with a couple of accelerator pumps first, usually starts on the first turn of the key.

Maybe some things to check:

1) Are you getting a good squirt from the accelerator pump in the carb?

2) The fuel pump push rod could be worn, causing a week pulse of fuel to the carbs.

3) I believe there is a anti drain back valve in the fuel pump which may be allowing gas to siphon away from the carbs.
    maybe try a new fuel pump?

Let us know what you find out.

I took my 59 Plymouth to the Ct Mopar night cruise, over 150 Mopar‘s in attendance, total of 400 cars.
It’s about 150 mile round-trip drive
My car ran great except for two issues
1) I have the in-line dual Carter AFBs in a stock set up.
After sitting a month or more, it takes a while to start, I can crank until the oil light goes out in short bursts, I do not get fuel the carbs, if I hit it with a dash of starting fluid it pops right over. After that the car will start the next morning and every other time until it sets.
Is this normal or do I have some other problem that needs attention, I was told that the fuel drains back to the fuel tank it takes a while for fuel reach the curbs??
I do not like to use starting fluid

2). Is it normal not for a 745 three speed tranny not to downshift when you approach a good size hill automatically?
I can step on it to the floor and get passing gear
These both might be normal problems, but I was looking for a fix ,to make it a better driver
Sorry for the long email,
Mark
