Hesitation at start and a *pop* throught the carburator!

I've got some hesitation at start and now a *pop* through the carburetor!

My '69 with a 383, headers, aluminum intake, electronic ignition and an Alberik carb has now developed some bad habits. It used to always give me a slight hesitation at start, but a I worked around it with a slight "flutter" of my gas foot. However, I did have it "breaking up" on me at rpms above 4500.

I had a friend come over and help me reset the timing as I thought it was running poorly.
We retarded the timing a bit, but now I've got a *pop* through the carb under moderate-hard acceleration. Gradually increasing rpms gives me no problem, but the hesitation on take off persists.

Are the two related? Should I just not worry about it and advance the timing to the "old" setting.

Any ideas are helpful!

It sounds like the timing is retarded a bit to much. what is your base setting?

sounds like its running lean and a little too retarded....
Remember the average response time to a 911 call is over 4 minutes.

The average response time of a 357 magnum is 1400 FPS.

Mine had that too.  Was going from a good idle circut and going lean in the transition.  might want to check the acelerator pump if it is a carter or eddy carb.

To find out if it is lean pull a plug or 2, if it is white or very light brown it is too lean.

Thanks-good suggestions. tonight I'll advance the timing a bit and put a little back to rich.

It is an Edelbrock carb that is relatively new so I'm thinking the pump is okay.

I'll keep you all posted.

Thanks!

 Make sure the firing order is good. Adjust the carb and replace the plugs.

This car was sold many years ago to somebody in Wisconsin. I now am retired and living in Florida.
