April 6, 201016 yr I couldnt figure out why i wasnt getting any response, backfires, and really crappy mileage in my baby blue 'roo. 16mpg. put the timing light on it and removed the vacuum line and turned the dist up and down. after watching all cylinders fire, set the timing at ave of 8*btc. #3 misfires occasionally (still wondering why). Thought the inside may have been gunked up and decided to spray it down. Opened it up and discovered, 1. the rotors and contacts were slightly corroded and sanded the rough stuff down. 2. It must have been a mechanically inept person working on it beore, but those little plastic pieces on the edge of the distro were inside blocking the movement of the mech advance. I put the little pieces back where they belong put it all back together and back on the road for a test. rev it up ovr 3500 before shifting, got a few backfires, and eventually cleared up. response is alot smoother across all gears and speeds down the hwy. The mpg should go up now, im expecting mid 20's now with what left in tank. If i have to, rebuild the carburetor next time i have a couple of days off.
