The chief gas a mega expensive glass matt bat always kept on a smart trickle charger as per specified by the battery mfg. It's a dual-coil pack, and I notice the front cylinder doesn't fire until after it starts. Wires looked good, maybe throw a new coil in it? Makes me wish I had a scope to see what the signal to the coil looks like. I gapped the plugs down to .025 from. 030

I'm getting a can of start fluid, see if that helps.
