This one is so damn old it actually has a Veglia spedo....but same deal. It's steady up to 30kph and then starts bouncing unless the Mobylette remains at a constant speed....
I took her out for 1/2 hour spin on the coast today before I start breaking down the front wheel to replace the rim. Runs much better than before, no throttle lag at all and the "stench" of un-burned gas seems greatly reduced so perhaps that was related to the timing as well. She seems to burn much cleaner.
Since I cleaned the chains as well, broke down the rear brakes and rear suspension, then completely re-lube it all no squeaks and a lot less drag rolling her when not running. I think I'm getting close to "like-new" performance.
Did experience a "very slight" cutout for just an instant once or twice....so again it may be that the replacement high-tension coil under the tank is a lemon.... I will do at least 10 laps around the town (about 15 miles) as a test before I will trust her for longer runs.
I attached a couple snaps before the over-haul and after. Still have not painted the body-work, waiting until I get all the mechanicals finish.
