Thanks for this. Yes, I can do this. It will reduce some volume in the bowl, but probably the simplest way to know if the pump has re-filled the carb.

5 seconds of cranking isnt all that much but could be longer than some like... if thats the case just break it up some, do 2 or 3 2-3 second cranks, thats what I do when mine goes dry after about 4-5 days of sitting in hot 80-90 degree summer temps, takes longer to go dry in cooler temps. Thats for my 2 cars with 1978 q-jets... my 81 with a CCC q-jet can sit for over a week if not 2-3 & it will start up in about 3-4 seconds of cranking, not sure why but the 81 is noticeable different.

Agree 2 or 3 seconds is not a big deal. I had it stuck in my head that continuous cranking is hard on the starter so have also used "bursts". My choke and fast idle are close to working so I will press to set and crank 3 seconds. Then repeat. I figure the starting sequence is designed to squirt some raw gas into the manifold so pressing before each crank makes sense to me.

Im considering a full intank pump set up like tanks inc, but until then & for the last ~10 years Ive just dealt with it by doing a couple 2-3 second cranks when needed, not really a big deal.

I just replaced my tank and thought about it, but not worth the money and effort to me either. My car still isn't on the road so it sits a long time between starts. If I drove it every few days, the carb might never dry out. Hope to find out!
