I have a 1969 Mustang Coupe 302. I was having problems with it bogging down, the tachometer was jumping around, it was dying, etc. I got a new set of points recently. This helped a ton. I also got some other work done to it as well as getting my 4 barrel Edelbrock Carb tuned. Now the car is bogging down sometimes still, and it stutters when I just have it half throttle or so. The plugs are still good, I have new points (they haven't slipped), the whole distributor is fine. Any ideas? I'm thinking it's either carb problems or the tuning, which should be ok. The car idles fine as far as I can tell, but it is cammed so I don't know for sure. Any feedback is greatly appreciated. Thanks for taking the time to read.

 

Get rid of the points first. You need a good ignition, especially with modern fuels. Until you're 100% certain it's not the ignition(ie, the points are gone) you can't be certain if it's carb related or not.

 

Bogging makes me think it's fuel related. How big is the carb?
