Pamco...isn't that an electronic ignition? Aren't they supposed to make it easier to start than points? I'm no ignition guru, but I have a lot of practice going back and checking to be sure all the basics are correct because I didn't get it right enough the first time. Now I can start it with the kicker using my arm. I suspect you have a detail out of place because the battery should provide plenty of spark power for the first bang. Go back and check timing, advance, spark plug caps, choke working, idle jets clean,...I'm sure there's more, those are just the recent ones that were my culprits!
Oh, and how 'bout accelerator pump jets, got those clean?
