I've racked my brain over this thing and I can't figure out what's wrong.
I did a full resto on this scooter, having replaced the wiring, CDI, stator rebuilt, and went through the engine. The bike is a 1979 model with a Sito Plus and a 24/24 carburetor with stock jetting. Ever since day 1, it's performed worse and worse. In the beginning, it would just be hard to start, maybe 5-10 kicks. Then it needed starting fluid. Then you'd have to change plugs, kick, then add ether. Now it ONLY runs on ether, dying out after 5 seconds.
-When I pull the plug, it is wet, so it's 100% getting fuel.
-I didn't run a battery for the few days of riding around when it *did* run in the beginning. Would this have fried something?
-Checking spark, it looks yellow/orange instead of white. Perhaps a weak spark?
The only things I can possibly think are that the magnets in the flywheel are weak, or that my timing is horribly off. It's previously run on these settings, which makes me not think it's a timing issue.
Any ideas? I'm totally stumped and don't want to start throwing money at problems I'm not experienced enough to diagnose...
