in my 69 ford e100 that has the 290 straight 6 it just started doing this but it runs rough and a stop unless the choke is pulled all the way out. so i did a pretty good tune up on it( plugs, wires, cap, rotor, ignition coil, fuel filter) and now it will start and idle but while in gear or under load it seems like one or more cylinders are dying out. can anyone help out that has ran into this.... thanks awolf

What about the air filter?

To me, this means you don't have enough fuel entering the engine. I would start with the carburetor. Perhaps a sticky float, or stuck inlet needle, or plugged jet or....? Might also change the fuel filter.

These engines have mechanical fuel pumps, and suck the gas from the tank. I had a dry rotted fuel line between the tank, and the metal line that ran under the car to the fuel pump. It didn't leak gas, but it did allow the pump to pull in air, and cause the engine to starve for fuel.

Sorry awolf, I was under the impression from your post that you solved the choke issue by doing the tune up you listed?

Also carbed vehicles will often have two fuel filters; one in line and the other (well still inline) but right at the carburetor.

My '66 352 has a filter on the bottom of the fuel pump, on the side of the block. It is about 2.5 inches in diameter and 4/5 inches tall, with a replaceable element. Spins off like an oil filter. If you can see down the carb, there should be a nice squirt of fuel when you rev the engine, if it comes out strong at first then peters out , the carb is probably fine and its a fuel flow issue. Usually when the pump goes bad, it will weep through the blown diaphragm, out of the weep holes onto the ground AND into the crankcase Rich

why not upgrade to a 300? you'd get way better fuel mileage, and response from a fuel injected 300 inline 6...

ok so i had my mechanic friend look at it and i have the 300 block in it and another thing i noticed before all this happened was that after driving for a while and would shut it off when i got back in it smelled strong of gas...kinda like the carb was loading up or like the ruturn line wasnt working properly. would that cause alot of this to be going on??? thanks all

Really? How could that be?

I wouldn't think so, it seems to me that the engine is running lean unless he pulls the choke out.

Sounds to me that the needle is sticking or your float has gone bad. Rebuild your carb, its so easy a caveman like me can do it, and it costs around $20. Rich

Yes Lincolndriver, it was in his original post.

I dissagree with jonzo, but am willing to learn.

That's interesting.

Did you look for vacuum leaks?

You need to run 12v switched from the ignition. Other than that, will it even bolt on?
