Just ran 50 mph up a steep hill. But, yeah, I think a new carb will make it better. Thank you guys!

She's running!!! I was not quite thorough enough with the carb cleaning, I guess.I pulled it back off, took EVERYTHING apart, cleaned every passage, and inspected all diaphragms. I think the slide bore is worn too much, so I will be buying a new carb most likely.

Alleyoop It has the same symptom with air filter on or off. I got it to run on the main jet by pulling off the air box and fiddling around in the venturi. I found this out by accident while I was feeling to see if the slide would raise by itself. i must have a clogged passage for the transition between idle and main jet.

Thanks twowheeler and alleyoop! Yes, there is an air filter on, and I checked the diaphragm on reassembly. I think I missed cleaning the mixture screw passage, so I'll try cleaning the carb again, and then check back in.

Hullo! I'm new to scooters, but not to bikes. I'm getting out of motorcycles and into scoots so I bought this 2006 TNG Lowboy 150. It was not running (wouldn't you know), but I was able to diagnose a bad CDI using another thread on this forum. It currently will start and idle just fine. I am able to get it to go on the main jet by partly blocking the carb venturi with my thumb, and then it will run at full throttle on its own just fine.
This is what I have done so far-1) replaced CDI 2) Removed carb and cleaned all jets and all passages that I could find 3) drained old gas out of tank and put in fresh 4) checked for vacuum leaks by spraying carb cleaner while engine runs.
Questions--could a weak spark plug cause this? Did I miss cleaning a passage? What's the little solenoid gizmo on the carb, and could this problem be related?
Thanks all!
