10% Ethanol will not start……no fire??

When they sit for a couple of months there is absolutely no fuel left in the intake manifold. It’s dead dry. Like starting a new engine.

When they are new and everything is dry it takes a pretty good load of fuel to get them to hit right off.

Four to six good pumps to the floor and it should start without priming it, IF what Johnny Mac asks above is correct as that’s the way I’m reading what you wrote as well.
