I have a 292 bored 60 over mummert intake and headers. Pertronix in dizzy. I have been running autolite 46. I believe i have around 10k miles on the motor since build about 5 years ago. I have a new avs2 500cfm carb. I have this weird hesitation that only happens in the higher rpm 2800 ish. Seems to only happen when i really get on it. if i ease up its not as apparent. This carb has capability to adjust the air flap for secondaries. Could i have it too loose? Also I have the accelerator pump arm in bottom hole for least amount of initial shot. Stumble off the line is bad in the top hole and simi in middle hole. I am not a pro at reading timing. would this be a symptom of too much timing? Also i am thinking of going to the autolite 45 to see if my engine likes them better. here are some pics of the plugs. thoughts?
