Mechanical fuel pump is non adjustable. Runs off of eccentric on the cam

Are you sure?

"Vapor Lock" is a much misused diagnosis. Which in most cases means, " It's something I do not understand, this sounds good, to "throw at you", cause you ain't gotta clue either!

What is going on on your end. Mega Detail is always welcomed here. Leave nothing out, what you have done (everything from messin' with screws etc.), History etc!

Got tuning tools? Know your way around your engine/ carb? A repair manual to reference by?

I'm old school. The rig you see me in below is 65 years young!

To start off let me say that we had a mechanic working on this car then walked off the job. So now we are having to have someone work behind him with parts taken off. On this 1975 lincoln town car we rebuilt the carb. And put it back in and adjusted (tuned it). Also did some muffler work. It started by bogging down and cut off in the middle of the street after doing the muffler/carb work. The mechanic who was working on it said that the fuel pump was good but the "lever" that comes out of the pump was loose and needed to be tightened then that would prevent it from cutting off again. He took off the timing cover and a small round cap (maybe 2-3 in round and 1-2 cm lip). Not sure how to put everything back together or tighten the "lever". Can we replace the eccentric on the cam? (Just a question I'm throwing out based on your previous reply) Or would we be in a better situation just replacing the fuel pump, or is that not the answer? I'm so lost right now and would appreciate any help you can offer. Also we do not have a repair manual for this vehicle and am not sure where to find one either. Thanks in advance.

Don't know your situation

FUEL PUMP--sorta an expendable Item!

http://www.autozone.com/autozone/parts/Airtex-Master-Fuel-Pump/1975-Lincoln-Continental/_/N-iof6dZ8vcz2?counter=0&filterByKeyWord=Fuel+pump&fromString=search&itemIdentifier=193326_199148_0_

Carburetor--1975 lots of wear--Rebuilding is a tough thing to do correctly, proper tools, vatting parts, internal adjusting that must be perfect....still using worn parts

A rebuilt one has been picked over at the reman place, only good parts are used...you usually get a 1 year warranty......Slap it on and with the proper meters and gauges adjust the, already close, mix screws...set the idle speed and maybe adjust the choke.

Don't turn in you core till everything is good to go!....You may need brackets or the number should the "New One" not work out!

Unless the muffler system is "Clogged" or restricted, probably not part of the equation

Elaborate on the "Mechanics" abilities, history, references, "Real Tools" (That one, has pride and takes care of).....I feel sure he is not a "Business".....That's OK, to try to use inexpensive resources.....I do too!

THEY MUST BE KNOWLEDGEABLE AND CAPABLE......Not just, "I an fix it, I can fix it"......Kid down the street with a go cart!

Sorta get a glimpse of me in this link

Let me know what you need, or need to know, I'm here to help....I try to case by case, do the best I can for you!

Let's try the BRAND NEW FUEL PUMP 1st.........May get lucky with the Carb!

Just found out the fuel pump is good, however the cap I was referring to above is broken. It has two holes in it now and I just got a new one and this one has a metal piece maybe 1/4 inch long (maybe smaller) that sticks into the fuel pump for it to turn. Any idea what I'm talking about or if I'm on the right track. Thank you so much. By the way, carb is working great. Now it's just making sure the fuel pump turns to do what it is supposed to do and figuring out how to piece these parts back into place under the hood. (Horrible having to work behind someone)

Allrighty Then!

Fuel pump does not turn. The cam in the engine makes it go up and down. Like a old water pump like in the kitchen in a turn of the century house.'Course the handle is inside the engine!

Can you send a pic(S) of the stuff you are referring to. Worth a thousand words!

Who's the "Head Mechanic" right now!

Here are the pictures of the cap I was talking about earlier and under the hood where the timing cover was taken off.

Before, I said eccentric on the cam---Sorta told you wrong!

This "Thingee" in the pic, is the eccentric that moves your fuel pump arm, up and down

Can't see the "Broke" in the pic, plastic bag kinda makes it hard to see.

Get it back on you might pump some gas!

Anything else damaged?

If you call around to some auto machine shops, might have a good used "Gimme" to replace yours!
