i think you should be measuring timing in degrees not rpm

I'm pretty sure it's at 8' right now. after TDC

There is a fuel filter on the frame rail. Just checked. I'm sure it needs to be replaced though.

No. In-tank pump is still there. It was pullin gas through it. Didn't see a need to take it out.

Why should I have to take it out if gas is still coming through it?

If you had tbi, and the pump is still in the tank and hooked up and pumping, it puts out about 9-13psi.

A carb only needs like 3-4psi(I'm not a carb guy so that may be wrong #).

So you need to install a pressure reducer, otherwise your spraying to much fuel into the carb, then into the engine...... which makes it run rich.

Some day when you sell that car you need to leave a piece of paper in the glove box with "www.cascadecrew.org" written on it. It's the merciful thing to do.

Time out:

Is there a mechanical pump on the engine that you are using?

Is the intank pump still wired up and wired to run?

The pump in the tank isn't running anymore. I have a mechanical fuel pump. Remember? I'm the guy runnin without a computer. Laughing

Just because you don't have a computer, doesn't mean you weren't using the intank pump. I had to clarify. Cause if the intank pump was also running in addition to a mechanical pump, you'll be getting way too much fuel and causing the problem you describe.

You're trying to suck a volume of fuel through a pump. The pump was made to turn, which is what gets you the volume from the intank pump. By sucking through the veins of the pump, there is no way you can get proper volume from your mechanical pump.

It will cause a lean condition under heavier load situations.

Oh. Well in that case, i don't think its running. I don't hear it when I turn on the car.

hmph. So I do have to take it out then?

my car wouldn't pull fuel through the disabled in tank pump. just use the smaller return line instead.

nonsensekid20 · Posted: Wed Feb 09, 2011 9:31 pm Post subject:

I can run fuel through the return line? hmmm. Then do what with the other line? plug it? Do you mean the vapor return?

sure, it's the redneck hack way. 1/4 inch return line will supply enough fuel for 300 rwhp, with a carb.

I thought I tried that and it wasn't pulling fuel through.

Another question. When I hit the gas it always has a flat spot. Is this related to the fuel pump? Or timing? Or something else?

I'm pretty sure I have the timing set good. So then all it could be is the fuel pump. Would putting a fuel pressure regulator bypass having to take out the electric fuel pump?
