Carb adjustments after timing change?
Hi everyone, when you advance the timing, is there any modifications you need to do to the carburetor?
I advanced the timing from 6 to 14 on my '78. Runs so much better, especially improved lower end. But, it is now REALLY hard to start. Wants to flood easily when I first try to start it after sitting a week or so. QJet is recently tuned and was working perfectly before I did the timing change.
Any suggestions?

Running about the same temp. Possibly slightly hotter. Not near a problem though. The car starts fine once it has run a bit, it is just the initial start after sitting for several days tha is tough.

Thank you for your post, Boofers. That was something I already checked. Gas squirts, and so is present in the bowls.
I am wondering if the mixture screws need to be adjusted, or even the choke "lean <--> rich". Maybe since the timing is advanced, it is now too rich, and floods. Thanks again. I will fiddle with the mixture screws, see if trial and error will get the thing to start next time.
