This is on a 926001-022942 Ariens snow blower
Came in for a service with some vicious surging. What I've done so far:
I cleaned the carb.
Two new after market carbs. Both still surge.
Drilled out the idle jet on the original carb.
Drilling the jet did improve things slightly. I guess I could keep drilling.
The engine smoothes out with choke. Compression test yeilds 60 psi.
I put a new plug in this and it has only run for about 10 minutes total since. I noticed the plug is a little black and has oil on it. Here's a couple pics.

I'm at a loss on this as far as eliminating the surging. Any help is appreciated.
Thanks.
