I picked up 2 bundles of slab wood for a neighbor yesterday (1.5 cord for $20, not a bad deal). So I'm plunge cutting with the 6401, and it starts farting out. Re-start was- push in de-comp., pull choke, 1 pull, choke in and 1 pull. Started, but as soon as you hit the trigger, bogs out. Saw dies. Do over with the same results until you get pissed and break out the 346. When I opened the gas plug, the pressure sprayed gas all over. After it cooled down, minimal pressure release, but it was still there. Where do I need to look to make sure this thing is venting in the future? Or is it another issue I'm overlooking? Thanks, JB
