So I have rebuilt the carb, in doing this I have found that the accelerator pump linkage had to be adjusted in order to get a longer stroke (now I can step on the gas without the backfire). So now that I have rebuilt the carb, the car starts right up and runs good at a fast warm up idle, but once it warms up it will not stay running. I am waiting for it to cool off so I can check the timing. Kinda hard to start the car and keep it running/check timing by yourself.
