OK, here's the situation: I bought my Taotao CY150-A, it ran for a couple of days, then just "died" on me as I was riding around. I replaced the spark plug (side of the road fix on April 4), but it still wouldn't start. My son ended up walking it the ~2 miles to the local scooter shop. In the parking lot, they put on a new spark plug boot; it still wouldn't start (electric OR kick start.) So, on that Wednesday, I left it there to get it looked at by the mechanics.
The following Saturday afternoon, the shop wheeled it in, and it cranked right up. No problems whatsoever idling or running. I drove it home, and it's been running just fine - my son even took it on a 30-mile-each-way trip to see his GF across the bay.
Same damned thing happened around noon - it just died while I was sitting at a red light. I was able to get it started, but it was very sluggish on takeoff, but would finally go (enough to get me home.) But it would stall if I let it idle, so I had to keep it revved up at the stop lights.
When I got back here, my son noticed that the air filter tube was loose, so we put it back on nice and tight, but it still won't idle (it just dies.) I tried adjusting the idle screw, but that's not helping.
I just pulled the spark plug out, and this is what it looks like, 9 days old:
Seems like the spark plug is fouled too much for being only (slightly over) a week old. Or is this normal?
What could be causing this issue? I really don't want to take it back down to the scooter shop - they're backed up for days - only to have it "magically start working" after they let it sit.
Also, the air intake tube is cracked all the way down the side, even through where the scooter shop put some gunk on it. I'm thinking that I need to get some JB Weld or or something, or else just go ahead and switch it over to a cone filter. From the looks of the plug, it seems to be running a bit rich anyway; wouldn't switching it over to a cone filter cause it to run a bit leaner?
that black stuff is carbon buildup from too much gas (running rich). could be from a number of things. fuel lines, petcock, carb, float bowl, but there's a lot of people here that know more than i do.
have you replaced fuel lines at all? has the petcock/vacuum valve ever been replaced? has it sat for an extended period of time without being used (6 months+)?
Yes, I was thinking the same thing - it appears to be running too rich. No, I have not yet replaced the fuel (or air) lines. The petcock/vacuum valve is the stock one AFAIK. No, this has been driven every day for the past week, and had two gas fill-ups already (plus I added gas today, thinking that maybe it was too empty.)
The spark plug is nine days old. So yeah, it's brand new, but I don't think replacing it is going to fix the issue.
I did assume it to be a new one as well and with that said, it proves there's excessive build up from somewhere caused within and like "Bradderheim" suggested, it may well be too but have you been throttling excessively as well during every standstill?
Clean the plug and bleed the system and try avoid over-throttling and see if that helps?

I might also check the jet needle. If it is an adjustable type, lower the c-clip on it to lean out the carb some. May also be a good time to check a/f screw. All the way in then two full turns out. Has the temperature been changing a lot where your at? Maybe the carb was tuned at one temp and now at different temps needs to be adjusted. They are very sensitive to climate changes.

same thing with the same scoot happened to a teen friend of mine in Clearwater FL. We replaced the plug and it still would quit and not start. I finally found a loose wire that feeds power to the coil. Not real loose just slides on and off with very little effort. I crimped it down so it fit nice and tight and it has been running great for 2 weeks. I have not pulled the plug since the new one was installed, she lives 50 miles away and I have not had to go back.
Now it starts, but it just won't idle. I need to let it warm up so the automatic clutch isn't engaged, but even adjusting the idle screw all the way down won't do it (I know, I know, that's a bad thing.) I couldn't find any loose wires.
Question: there is what appears to be a drain hose coming out of the carb, and it leaks gas sporadically. I'm assuming this isn't normal...?
You have a couple of problems: 1. it is running rich. 2. Your valves need to be adjusted, the dieing out at low rpms(coming to a stop) are classic symptoms. So First adjust your valves to TOP intake Valve to .004" and BOTTOM EXHAUST Valve to .005" or you can also set it to .004" your choice.
Then turn the Fuel Ratio screw Clockwise until it stops and then Turn it COUNTER Clockwise 2 turns (since your in Florida and its hot you need less fuel). If it IDLE to low TURN the IDLE SPEED SCREW Clockwise a little to bring up the IDLE then after it warms up about 5 minutes you can Fine tune the Carb.
When tuneing the Fuel Ratio Mixture you want the HIGHEST IDLE you can get out of it. So from the two turns out 1. Turn the Fuel Ratio Screw 1/4 turn Counter Clockwise and wait 10 or so seconds to allow the motor to catch up with the new Setting. a. If the idle goes up repeat #1. b. On the 2nd or more repeat of #1 the Idle goes down or does nothing THEN TURN it 1/8 Clockwise, this should be the highest Mixture you can get out of the Fuel Ratio.
*** If on the VER FIRST 1/4 Turn Counter Clockwise the IDLE GOES down or does NOTHING REPEAT #1 But CLOCKWISE ***
If at the end of the setting the idle is to high LOWER your idle using the IDLE SPEED SCREW Turning it Counter Clockwise will lower the Idle. You DO NOT want the Rear Wheel Spinning while IDLEING.
You should be able to then Give the THrottle a Quick Twist the rpms should climb without any hisitation or bogging and come down to where you set the idle. Wile
FROM THE BOOK OF KNOWLEDGE: THE THINGS YOU DO FOR YOURSELF ARE GONE WHEN YOU DIE, BUT THE THINGS YOU DO FOR OTHERS REMAIN AS YOUR LEGACY.
I don't have any feeler gauges to adjust the valves. Would the valves and the A/F Ratio be what's causing it to run too rich? Why would the scooter run for over a week just fine, then suddenly die like this (again)? That doesn't make sense.
Guess I'll hafta run out and find some feeler gauges in the morning. Hopefully I can find a cheap set.
Agreed, but having never done a valve adjustment, I'm trying to figure out how to do it. I mean, I could take it into the shop, but that would take a while. The feeler gauges are like $8 or so, not a lot, so no big deal. I've Googled how to do it, found a few guides, but obviously none of them are exactly the same engine I have, so I have to figure out what to do.
Wish there was a scooter club around here like my old Miata club, we used to meet up once a week, and we'd schedule tech Saturdays, where we'd all pitch in and work on each other's cars based on what we knew how to do.
Well, that helps somewhat. I agree, I'd much rather watch and help someone at least the first time. But unless 12string has some free time today, sees this, and is willing to help, looks like I'm on my own. I at least see what needs to be done, but I'm gonna hafta research it more and watch some other videos first - I don't want to screw anything up.

marklorenzi: I just bought one of the Fleetwoods. They look like a clone of the Honda XRM's they sell overseas. It is in transit now and I should get it this week. I will try to post my experience here. Call me the guinea pig hahaha.
