Thanks
@txlabman aka Charlie but you might change your mind after reading the below LOL
While the sight glass wasn't leaking it had something "gooey" around the glass as it meet up to the brass slip nut. After getting it all apart, I found inside the slip nuts was string, which isn't the first time I've see this type of a "seal". I image the "gooey" stuff was some kind of old sealant. After a little cleaning, I got the sight glass re-installed with new silicone seals.
I also installed one of the governor bands I got from weedensteam.com. I had to remove the shaft to slip the band on and while I noticed the screw for the shaft seemed a bit loose but I forgot to revisit it. That was a mistake and brings me to my calamity, I seriously freaked out and was yelling at my stupid self for a good few minutes. I had just waited overnight to let the piston end cap dry from using some "Permatex 59235 High Temperature Thread Sealant" on its threads and was testing the #14 out. After bringing the engine up to near full speed the shaft's screw worked its way off. Then in a blink of a eye the lead ball that ties to piston's brass rod flew off across the apartment!
That little lead ball / pivot / shaft combo wasn't damaged - so I dodged a BIG bullet. On the other side where the screw goes in for the shaft, it was okay too. So I used Loctitie 609, Medium Strength to reattach the lead ball to the piston's brass rod and used a dap for the shaft's screw. Hopefully when I fire it up later all will be okay...
