Det 64,
My 216 only takes a couple of pumps (like 4 or 5) and a little bit of choke and it starts right up.
My truck is not a daily driver yet so it might only get started once a week.
So ya know what worked for me...I had a Double action glass bowl fuel pump on my truck to replace the one that was full of varnish after sitting. I ran that pump for a couple of months...it started to leak and acted like it was putting out too much pressure as the carb was always leaking. Since I plan on driving my truck regularly, I went with a new fuel pump...I bought mine at Car Quest. No more leaky carb or leaky bowl on the fuel pump. I wish I had bought the modern one the first time....live and learn...
