Question I have a 71' T-Bird, with a 429ci thunderjet. my folks bought it new and recently gave it to me. it has 57 thou's origl miles on it and always been gararged,all previous maint. was done at a ford dealership,( wished I could afford that) anyway it started to run rough,so time for a tune up. my friend offered to do this,for favors I had done for him,when he returned it he said it would not idle or run right. he had replaced,plugs.wires.cap.rotor,points,cond's and adj carb.,checked timing. I checked his work,and it sounded like crossed wires,checked firing orderand timing,reset poits,and found and fixed three vacuum leaks,vacuum now at 17-18. when started(cold)it loads up and dies,on restart when It fires,up you have to keep rpm's up until it warms up or it load ups&dies and be real hard to start and even backfires up through the carb. rebuilt carb and still the same!HELP!
AnswerMr. Murrell,
First, you have a carburetor problem. It is burning too rich. I would go to Auto Zone, Advanced Auto, Napa or some other reputable automotive supply store and purchase a carbureator rebuild kit for your particular model carb. If it is back firing, it sounds like you may also have a timing problem. It should be 8 degrees before top dead center, but this is off the top of my head. I f you would like me to look this up for you to be exact, please contact me again. I hope that this helps and if you need further assistance, please do not hesitate to contact me again. Good luck.
