I'm stumped. I finished rebuilding my 330 with new boot/fuel line etc.
The chainsaw runs great when I'm doing normal bucking, but when I attempt an undercut, the engine starts to cut out immediately (almost as if it is losing spark). And then if I decide to go back to normal bucking, it runs fine again.
I agree with Undee on the wiring. I believe you can pull the muffler to take a look at the switch wires. I've seen them bare in the past. Undercutting could be shoving the muffler back against the switch wires.

You guys are absolutely correct. Thanks. I took the muffler off and the muffler shield was rubbing on the switch wire when the bar gets pushed down. I've never had that happen before. I learn something new every day.

Ditto on the wires. I just finished up a 330 with the opposite problem; the ground wire was broken internally, so the switch wouldn't work. I like to zip-tie the leads over a bit closer to the spark plug wire on reassembly.
