| Post subject: | Hesitation off idle |
I'm running a Carter BBD off of a 1976 Dodge Truck 318. On Saturday, I got the metering rods and the accelerator pump adjusted quite close to stock specs, and my car was running quite nicely. I also advanced the timing a bit (by ear by loosening the bolt and turning the distributor a bit) On Sunday, I started it, and it had a hesitation right off idle - even after it warmed up, and I didn't change a thing. It was somewhat cooler and more humid - I don't know if that has anything to do with it. So I made adjustments to both the metering rod lever and the accelerator pump, but it doesn't seem to make the hesitation completely go away. I did put the distributor back where it was on Saturday. Any ideas what I should do to get rid of the hesitation? It's more noticeable if I step on it harder - which is a bit scary if I'm pulling onto a busy highway. |

With the engine off look down the carb and activate the throttle. How much of a pump shot do you see squirting down the throat? It needs to be a very strong shot of gas to eliminate the bog off idle. How much initial timing do you run? 6 degrees or more? |
