Complete tune-up would be in order; i.e., spark plugs, points, condensor, Make sure you set the correct gap in the points and the plugs. Also might as well throw in some spark plug wires. I wouldn't suspect the coil but what the hey..change that too!
What can cause older engine to misfire and have lack acceleration?
i have a 1971 mustang with a 351 cleavlend and it runs good but when accelerating it has little miss fires and when i get going above 20 and give it a bit of gas it seemes slugest. it makes noice but doesnt really throw you back in the seat like it use to. i put a new timing chain and cleaned the carb . it does have what lookes like the stock coil though. so can you help me out ?
