While still waiting for parts for the other projects started and stalled, I decided to rebuild the carburetor as I felt it was possibly, slightly gummed up. Whaddya think? I was not even surprised when I removed the float bowl cover and found--guess! Yeah, more silicone from the previous moron-er, I mean mechanic. I spent most of the morning cleaning and blowing out jets and passages until I was sure it was a clean as it was gonna be.
