This is one that helped me last night when I put the carb on the Buick and fired it up. One day back awhile I was firing up the car for the first time after it had sat for years and right as I was cranking it an old friend came walking into my garage. This guy is a motor guy thru and thru and the first thing he asked as he stopped me from cranking was "Did you fill the carb with gas?" HUH? How do you fill the carb I asked and he showed me how you pour gas into the bowl thru the vent. Sure enough, it fired right up and kept running.
I did the same thing last night, it fired right up and ran.
