Finally got a chance to mess with the "new 129" (the former 109). The carb throttle shaft was so loose that the engine needed the choke about half out to run, and even then it was lean, according to the glow from the muffler. Rebuilt a carb from the shelf, put it on, and it didn't want to start. You could hear the pffft, pffft, pffft, pffft each time, and smell unburned fuel, but it wouldn't take off. Checked the points, looked good, but ran some paper through them anyway. Good. Set the gap from it's .025" to .020. Tried again, no go. Went to check the timing, but there is no mark on the side of the flywheel. Hooray. Set the plug gap on a new plug. No go. Changed the plug wire with one from another engine. Still stubborn. Hooked the charger to the battery for a while and drank a cup of coffee.
Went back out to the garage, and had it going in about a minute. Want me to tell you now, or do you want to guess?
I think I'll let you guess.
I had no belt-driven implement handy, so I let it warm up, then did some wheelies to "put a load on it" before doing the final carb adjustments.
