Got home and cleaned up the carb really nice. Also cleaned the air filter with the carb cleaner. I put all the new rubber bits on, and added fuel. Oooh, this is exciting!
After many attempts, it actually DID start! The idle was way too high, however, due to a throttle cable that was too short. This meant I had to replace the cable, which wasn't too hard, really. As long as you're just doing the inner cables. With the new cable in place, I tried to start it up again, but with no luck. I've read that the condenser is often the problem in these situations, so it became time for trip #3 to Scooters O - to get a new condenser.
A few hours later, and I've got the condenser installed. First, I went to check the spark to see how much BRIGHTER it would be with the new condenser. Well, no spark at all now! I don't know what's going on, but I am packing it in for tonight. Maybe an evening off will make things fall into place?
If this keeps up, I'm going to quickly throw in the towel and have them fix it down at the shop.
