fuel pressure with eddy 1407 carb.

[7dart0]

Are these carbs really that finicky with their pressures? I recently rebuilt the carb and now their is fuel dripping out of the venturis and it won't idle. I'm running a carter strip mechanical pump. I bought the carb used and there was alot of junk in it when i opened it up.

thanks tom

As I recall the strip pump puts out upwards of 8 psi? You should regulate it down to 6 or 7.

Did you set the float level?

I have the 1405 regulated to 5.5
they are that picky yes.

 

[Bulldozer]

5 to 5.5 is perfect

yes i set the float level to edelbrock's recommendation.i just received a regulator in the mail so i'll plumb it in and see what happens.

i have found that Carter AFB and the eddy clone like 5/16 float level. stock call out is 7/32 i think. i had a 1965 300 L 413 AFB that plugs was a little lean. when i went to 5/16 float level it was just right. EDIT; i just looked at my 1982 Carter AFC performance products cat. form 3209. on page 27. it says to run float level at 5/16.. and on page 31. is a needle ans seat chart showing 5 differant seat sizes. the 25-1091 .125 dia. will flow 110 gal per hour at 6 psi.

Years back I bought a new 1407 for my 68 340 Dart that I once had. That carb gave me fits at idle until it was warm up. I tried a manual choke cable the the Eddy electric choke, but when ever the choke was partly closed at idle, raw fuel would flow out of the the main venturi tubes. I called the Eddy tech line and they said that the fuel pressure should not be any higher 5.5 psi. I added a fuel regulator, but it did not seem to help.
