I hate this thing. More fouled plugs. No difference really with the carb rebuild. We did however find that the plugs are getting good spark all the way till it dies, so it looks unlikely that it's a spark issue. We have a couple carb sitting around that we're going to try tomorrow. Even if it runs like crap, but constantly, we will know it is a problem in the carb. I'm not throwing parts at it yet, but I'm getting close.

This doesn't sound like a dirty fuel filter issue does it?
