Just wondering if anyone has any ideas... I got my carb back from a company that rebuilds them and I installed it today and it was doing ok i guess for a little while except that when you get in second gear and wind it up it starts cutting out or sputtering...then once you go into third it does ok until you get on it hard trying to pick up speed and then it will sputter again. It idles fine and seems to do ok in first gear. Dont know what to think... It also doesnt start very well it will back fire through the carb sometimes.
How old is the vacuum advance on your distributor? try advancing the timing and see if it gets better if it does you may have found the culprit. Did this happen before you had the carb rebuilt?
Bad cold start is likely choke setting. Pulling good in first gear, but bad at the top of second and third could be fuel starvation, ie, pump unable to keep carb bowl full. Backfiring through the carb could be timing or valve lash, or a bad inatke valve/seat. Done a compression check and/or idle vacuum check yet ?
I checked the Plugs and they arent Black or Fouled out, I did install a Inline fuel filter because the guy who rebuilt the carb told me i should do you think this could be the problem? Jeff, I dont know old the advance on the dist is...I tried to turn the dist to adavance the timing but it will not turn...i loosened the two bolts on the dist and it is either frozen in place or doesnt supposed to move not sure which. I dont think its fuel starvation because if you take the breather off before starting the car and pump the accelerator it will shoot a stream of gas out the venturie about ten feet! It was doing this before i had it rebuilt too i think maybe the little hole that the gas comes out of is too big or something on that not sure. I'm getting a little black smoke out the tail pipe when i race the engine but not alot just a puff.

It does have points but they look good not fouled i may try to set them but it idles good so i thought that wouldnt be the problem?
the contact areawhere the end of the arm that opens has a little pad on it hits the other pad on the fixed peice, they can get burned or blisterd especialy if someone leaves the key on while thae car is not running. the spring that closes the points can also get weak. check the gap also. about .0017"-.0018" i think that how you do 17 to 18 thousanths. will get you right at 50 degree's dwell. but im also thinking normal points in 60 cars . might look at the contact area for being burnt and wait for a 50s points expert.
Try spraying some PB Blaster around the base of the distributor and tapping it with a rubber mallet you may have to reapply several times to free it up,seems Fords have a thing for frozen distributors I have found when ever installing one to apply some anti-seize compound around the contact area.
I will try that Jeff thanks, I talked to the Guy who had my carb rebuilt and he told me he thinks it is the timing... The thing is I have never seen a carb shoot gas ten feet from the venturie...It just doesnt make sense. While the engine is ideling or even when you rev the engine the fuel sprays down the carb from the venturie like is should but when you kill the car and then pump the accelerator it shoots 10 feet. Im beginning to thing somone must have drilled the hole out to get more gas or som,ething and screwed it up. I wonder where i could find that piece? I will take a pic when i get back in and see if you guys can help figure out what that part is and if they sell a replacement. I call it the venturie but it may be called something else.
Backfiring through the carb indicates a timing problem. Check the firing order, then re-time the engine following the procedure in the shop manual. Don't have one? Get one. Backfiring through the carb is also the primary cause of power valve failures. Black, fluffy plugs and black exhaust pipe is a good indicator that your power valve is damaged and leaking. One good backfire will do it. The accelerator pump shot is adjustable on most carburetors. If yours is too strong, and it appears that it is, adjust the carburetor linkage to reduce the pump shot. Adjustment procedure is in the shop manual. Don't have one? Get one. Good luck.
My spark plugs are clean so i dont think it is getting too much gas, i think maybe it isnt getting enough at high rpm's.
Well, Me and my dad got under the hood today and adjusted one of the the valves (It was ticking) and adjusted the timing, I took it out into town and romped on it and blew black smoke like a cloud out of the tailpipe the first time but didnt do it again aftewr that and seems to run alot better! It didnt cut out when i got on it when going into 2nd and 3rd. It still starts a little hard but runs a hell of alot better. The PB Blaster worked great getting the dist to move (thanks Jeff) and I also put my new steering wheel tires and rims on and I must say I never thought tires and rims could make such a difference in how it drives! its alot tighter and with the 13-1/2" steering wheel it drives almost like my new pickup. I cant wait to get the aerostar springs in and a new V8 this car will rock! Thanks for you guys help and ideas on what to look for.
