Well, let me start by saying "Happy New Year, blah, blah, blah." On to the update. I found some new stainless steel screws and lock washers at the hardware store, wire brushed all the internal parts for the variator, lubed it, and stuck it all back together. The variator works great now and I've managed to get my little PA50 up to 12 mph, but I've still got a problem. The ped runs great once it starts, if you leave the throttle alone. The engine will progressively run faster and faster until it levels out. The problem is when you twist the throttle, it speeds up for a second, then bogs badly, then almost dies. If you give it a minute it will speed up again. It acts like it can't deal with the amount of fuel that's being dumped into the cylinder. I am going to disassemble the carb and clean it out again. Anyone got any thoughts on what's going on?
Also, it was running really smokey and fouling the plug when I was running the mix at 32:1. I'm running it at 40:1 right now. Is this enough oil? I also increased the gap on my plug and leaned out the carb. After running it for awhile, the electrode on the plug is a light gray color. Am I running too lean? What should the plug look like if everything is adjusted correctly?
On a happy note, I managed to score a pair of original PA50 mirrors, which I promptly stuck on. Does anyone have any of the plastic cover parts they'd like to sell.
Damn this is a long post. :)
