After futsing around with the carb everyday after work, I gave up and took the truck to my mechanic. Turns out it wasn't just me, which does make me feel a bit better because I began to get really frustrated. Admittedly I haven't worked on a 720 in 25 years but I didn't think I forgot that much. Anyway, after trying to source the parts for the carb, we came to the conclusion just to get a Weber and be done with it. Since it was already at the shop, I let him do it. The perks of being a bit older and having a few extra bucks so you can say, just do it. Drove it home and runs like the 80k mile champ she is. Good grief, just awesome. Now that the main mechanical issues are freshened up, time to start looking at the future of the truck and where we go from here.
