The Stovebolt Site Forums The Shop Area The HiPo Shop edlebrock carb help please!

I have a Edlebrock preformer 1406 (600cfm electric choke) on a new 350 crate engine. When the engine is run and then shut off, restarting is a pain. It seem as if the carb floods. The fuel pressure is ok so I'm assuming its either a stuck needle or float thats not set properly. I figure I'd check with ya'll before i change anything. Is it possible that the stock jets and metering rods need to be changed? the main jet is .098 and metering rod is 075 x 047.

Thanks for the help

After you shut it down look down the carb. throat. If gas is dripping from the discharge nossels you have a float or needle valve problem. It,s possible one of the plugs in the bottom of the carb are leaking but not likely. The main jets & metering rods control the air- fuel mixture but would not cause flooding after shutdown.

Mac,

I can't offer help, but will say that the foreman at work had a 350 engine installed in his '70 something pickup. He too bought a brand new 1406 Edlebrock carburetor...it did the SAME exact thing. I don't know how he resolved it other than to buy a new Silverado.

I’m using an Edelbrock also and was in on a discussion this past weekend with some others who are running the same. They have had good results putting in a fuel pressure regulator. It seems that the Edelbrock likes the pressure down around 5 lbs and most of the new pumps put out somewhere between 9 and 14 lbs. I did go the Edelbrock web site and they mention to use the lower pressure. I haven’t tried it yet but you may want to keep your ears open for that. In looking up pressure regulators there seem to be a wide variety but also a wide price range.

Just one of the wonders of the eclones. The fuel valves are too large. Everyone wants big fuel valves for maximum horsepower.

However, try this link, the method may help you:

Definately put in a pressure regulator set at 4-5 psi. Edelbrocks are really touchy when it comes to the pressure.

I just put the same one (1406) on my 69 truck. I'm very pleased so far. I have not had any problems at all.

Handymamac, are you sure its flooding? If it is then read no further but if you find its not flooding then maybe its like mine? I have had the 600 manual choke on my 350 for 6 years and no problem until lately. Now it is a ***** to start unless I pour a drop of gas down the carb. Carbking suggest the fuel may be "vaporizing" from the heat and also that it could be the accelerator pump. I did some reading on a link carbking listed. I think its the pump so I ordered one yesterday and it laying in the shop for me to put in. I would have put it in today but got tied up beadblasting some stuff for the panel. I'll let you all know maybe tomorrow?!!

Achipmunk, I replaced the acc. pump on my 650 w/manual choke & it was fairley easy, just becareful with the needle seats
etc. but I found out I still had the gas smell problem & I have
to pump the pedal about 5 x before it will start...
Does anyone know how much pressure a stock fuel pump puts out ! How about the right fuel pressure regulator to be used
(say from Jeggs or...) !
