/6 runs great, randomly stumbles and dies...???

Yeah, I was thinking fuel too. When it first happened, I thought timing slipped, because of the way it acted and how sudden it was, but once I got it running again, it seemed more like fuel.

What you're saying makes a lot of sense to me... I will do that. It needs to be done either way. Pulling the tank is one of the few things I didn't do that I should have done immediately.

My other thought was due to same thing, the new carb got plugged with crap and is acting up, which still could also be.

Anyone else with any thoughts? But yeah, I'll check fuel at carb, then clean out tank.

Thanks!
