I bought the T-handle driver. Nice, tho from Jina. I went to work on that stubborn lower screw again today. I was armed with five items from the pawn shop. Cost me all of three dollars. Two nail sets, a very slim punch, a small chisel, and a screw driver. After another hour of tickling that screw with micro- chisels, (made with the grinder),it let loose and came out. This was my first time extracting a screw this way, and I'm here to tell you , it takes a lot of patience. But once that baby budges, it's a great feeling. So now I need to get the oil spinner apart, get the new guts in the carb. Keep my fingers crossed about the petcock rebuild, and then...maybe take a spin.
