Tuning a 350 with Edelbrock Carb

[grandall1972]

Sounds kinda like the accelerator pump may be bad or out of adjustment. Does pop back through the carb when you try to rev it? Also, maybe the EGR valve is stuck open.

Doesn’t pop back through the carb. Don’t think it has an EGR valve.

Accelerator pump is probably the problem. the plunger will get hard and not seal properly.

will check it out, looked clean but didn’t feel it to see how it felt.

Rebuild kits are simple on the Edlebrock. Double check the vacuum advance from the carb to the distributor is in the right place.

Getting a tune kit and possibly rebuild kit next. Vacuum advance is in the right place.

Sounds like it’s starving for fuel. Shut it off and get a visual of the fuel flow through the carb in both the front and rear bowls. Do this manually with the engine off. You should be able to see the fuel spray in both front and rear. If there is a fuel blockage you will get too much air and cause the stall.

Will look again and confirm.

Needs faster distributor advance, try to get total in at under 2,000. Why are you not using the vacuum advance? Can we assume stock cam ? turn the idle up a hair. Are the plugs right ? right firing order ? Do you have enough voltage ? 13.5-14 running ?

This sounds like timing issue to me. Try putting the vacuum advance back to stock. Are you using the stock distributor?

Vacuum advance is being used, was disconnected and capped when setting the timing which is what every site I looked at said. After setting the timing I connected it back.

Accelerator pump or floats need adjustment .

Just my 2 cents

Also ...

I put a new fuel filter on before and crap from the tank clogged it up fast .
I felt stupid when I figured it out

thanks. The 4speed is why I bought it.

Yeah they always seem to suck me in too!

Firing order is 1-8-4-3-6-5-7-2

Here is how the distributor is wired up, which is in the correct 1-8-4-3-5-5-7-2 order, but does the location look correct? Timing with the light is dead on so, I’m guessing it’s correct.

What I’m seeing online looks like I’m 2 spots clockwise from where it’s supposed to be. Would it run if they were all this far off? Especially smooth at idle and timing was easily set?

Note, I put the wires back were they came off of when I did the plugs and wires. As always replace one plug, remove and replace one wire.

Tried setting it up as pictured online and it would not start.
