Son dropped me off @ my workplace today (Sunday) to pick up my bike. The pull start rope wouldn't retract, so I loosened the mounting bolts and rapped on the housing until it retracted. I readjusted carb to stock settings, so now throttle response is smooth as butter. Rode to Jack Box for breakfast. Pull start jammed again, and I noticed two mounting bolts had fallen out. Removed pull start assembly and loosened center pivot bolt. Made notes to replace missing mounting bolts. There are two one-mile, medium-sized hill to reach home and a 200-yard super-steep hill. The bike took them on easily, never having to use 46.4:1 first gear. Second gear @ 38.2 :1 worked well enough, even from complete stops. I've been cruising in 7th gear on the stretches, which is 17.73:1.
