10% Ethanol will not start……no fire??

Some updates to your responses. Good info on the Ethanol, especially the hydroscopic aspect...thanks. Yes it is a good electric fuel pump, with dual Fram filters coming out of the tank and a full return line. When I go to start I turn on the fuel pump and let the pressure come up to a steady 6.5 psi, which would fill the bowls, acc pumps are working just great. Have tons of spark, but the only way to get it to start after setting for a couple of months is to squirt fresh fuel down the carb. I was just filling the primary bowl with fresh fuel thru the vent tube for a while, before turning on the pump, and then giving it a couple of shots with the acc pump, started right up, basically just look at the key and it would fire. I run about about 24 initial degrees (big cam) and I believe I am at 34 total. Transfer slots are square front and back. I will start adding some Staybil type stuff to see if this helps and just keep doing what I can to improve the situation. Thanks to all.
Just to be clear... you can turn your pump on, build pressure, then.....pump it 15 times, physically watch the acc pump squirter shoot fuel into the intake, and it still won't start?

Are your float levels full in this "no start" condition? How long are you letting the pump run?

If your acc pumps are shooting fuel when you pump it...it should start. I don't think they are functioning if you can't pump it and get it to start......
Does the carb have a choke? If you are content, then that's good, but seems more is going on.
