Hi Tom,
Yep, good point as it does have a compression release. I haven't checked the valve lash yet, but want to prepare ahead of time so I can just finish everything in one shot. Basically, the machine runs fantastic until it has a heavy load on it for a while, then it turns into a missing sputtering mess until it cools back down. I originally thought I was having carb issues and blew money on a genuine new Tecumseh carb.
