Well, I messed with the carb again today. I had previously taken off the two plates and the needle and soaked in toluene. Suppose to be better at dissolving gunk than mineral spirits. Put it back together and it still wouldn't run right. So today I pulled both covers AND the little screw holding the spring and pin down and soaked everything again. MISTAKE! Putting that spring back with the little pin was a PITA! Naturally, I lost the spring on the concrete floor not once, but twice. Then the pivot pin and the conical pin. Finally after finding everything a last time, I put white paper on the floor to start the assembly. After all that's where (floor) all the parts wanted to be. Multiple attempts were made to get all in the right place to put that little screw in. Bad hand so I finally used small strips of duct tape (modern day bailing wire) to hole the pins and the spring in place. Finally got the saw reassembled.
The saw started up and ran strong, but only at 3/4 throttle. I've got some limbs to cut up tomorrow to see if the saw bogs down under load. But I don't understand why the saw starts to sputter when the throttle is pulled all the way. Pluggage still there or re-tuning? If problems persist, I'll just opt for an aftermarket carb. I know you recommended a Walbro, but I think I'll put the same style on. As you can tell, I don't have the experience you guys have and I don't feel comfortable drilling new tuning holes and trying to tune it. Keep it simple for me.
