Thank you for the welcome. I'm an old motorcycle reject. Rode for 30 years but hips are bad and I can't mount the darned things anymore. Only 158 miles on the scooter so far. I have done nothing but mess with this scooter for the last three weeks. In desperation, I took it to a local Chinese motor scooter dealer and told him it runs like chit, yadda yadda yadda. I hope to get it back somtime later this week. I told him to set the mix, stop the fuel leak and adjust the valves. We'll see how that goes. My next project is installing a neat little motorcycle radio and speakers. They are in matching black and should fit nicely on the dashboard piece which goes around the steering if I can figger how to remove it. Thanks again and I hope to learn a lot here. Ernie

My MP250A has a defective enricher. It is stuck in the extended position. When I installed a new identical enricher, I could not find a place to connect the green and the yellow wires. On the original defective enricher, those two wires were connected together.
I heard somewhere that this is from a previous Yamaha design which required those two additional wires but the JCL does not need them to be connected.
So should I connect the green and yellow wires back together and plug the red plastic connector into the white plastic connector?
After I changed the enricher, the scooter is even harder to start and stalls at stop signs unless I maintain a tiny bit of throttle. Does this sound like the Chinese tuned the carb so it would run with the defective enricher and now, with the new enricher, the mixture is too lean?
Thanks in advance. Ernie
