I've been working on my 150cc scooter for a while, now. It is a 2007, but has been sitting up for years, so it only has 750 miles on it! I had to replace both brake master cylinders, changed all fuel and vacuum hoses, and just put on a new carburetor. I thought I had adjusted the idle mixture screw correctly, adjusting it slowly until it reached peak speed. The vacuum hoses are connected via the original configuration, using the charcoal canister and all. It is difficult to start. It will idle for about a second, then quit. After 6 or 7 tries, trying to twist the throttle quickly before it dies, I can finally twist the throttle and get it running. The idle speed seems fine. Once I get it started, it runs great. I can go to start it a few hours after running it, and it starts right up. If I wait overnight, however, it is difficult to start once again. Any thoughts? Could my mixture screw still need adjusting? Should I scrap or plug up any of the vacuum hoses? If so, which ones?
