50cc Chinese Silver Bashan- like a Tao Tao. Hey guys so I was having trouble with my kickstarter and electric starter here itistheride.boards.net/index.cgi?action=display&board=50ac&thread=875&page=1#8303 and decided to call a friend about the problem who knows more about motors than me. I showed him this video and he told me the problem with the electric starter was that it was not engaging the gears. He suggested that it could be a solenoid issue but he thinks it also might be something else. He doesn't know moped motors though, so he is unsure of what that could be. His guess is that the starter motor and kickstarter share some part in common and so the reason the electric starter won't work is because the kickstarter won't work. Thoughts? Do kickstarters and electric starters hold stuff in common? A NOTE ON THE KICKSTARTER: I detached the lever on purpose because it was getting in the way of the kickstand. The kickstarter is broken, shows no resistance and just hangs limply at the side. I'm hoping to fix the electric scooter as I have neither the time, money, or skill to fix it right now, and I only need this thing to last 1 month more before I move cross country and leave the hunk of junk |

The kickstart has a half gear on it that connects to another gear that connects straight to the shaft of the engine.
The electric starter motor is connected to an engine gear that is connected to the engine shaft.
That's the only connection there is. They are both connected via gears to the main shaft of the engine.
Oh... and the kickstart doesn't engage until you actually kick it.
So it's not even connected at the moment.
Sounds to me like the starter is cranking the engine and you are not getting any spark.

Okay, I'll check the spark plug. I had trouble with the spark over the summer, and I forget if it made a sound like this or not. I did check the spark a couple of weeks ago, and it seemed to be running kind of rich, a lot of black residue etc.

Here is a video of what your kickstarter looks like inside. The Way yours just rotates probably is the spring is broke behind the half moon gear or it came off the stationary stud.
Alleyoop
Your Electric start is working it is turning the Crankshaft and your piston is moving up and down. Take the Spark plug out or if you have a spare just take the boot off the one on the motor and stick it in the Boot Cap and then HOLD THE PLUG AGAINST the VALVE COVER and crank it and see if it is firing. If it is firing then it most likely is a Fuel Delivery problem.
So check that first then if fuel delivery problem I can guide you to checking and adjusting the carb.

Awesome, thanks for the guidance. I tried to open up the kickstart case, to get a look at the inside, but one of the bolts is pretty shredded from a previous botched repair attempt, and plus the gasket sealant makes it pretty hard to pry off. That said, I'll do a test on the spark plug and see if it's working.

Turning the engine over slow. Need to charge the battery.

Hmm... A 150cc CVT is slightly different than a 50cc... did not know that.

Turning the engine over slow. Need to charge the battery. The battery is brand new. The other one, as you remember, was having trouble so I exchanged it on warranty. The lights etc are strong and the fuel meter doesn't dip when I push the starter like it does on the low battery. So I tested the spark plug and it's sparking fine. An interesting thing is that when the spark plug is tested against the metal frame it doesn't do a whirrwhirrwhirrwhirr sound. Instead it just does a long continuous whirrrrrrrrrrrrrrrrrr sound. In the process of trying to get the spark plug back in it's socket, the stupid thing dropped down inside the engine... case? I guess thats what it's called? There's like this plastic and metal thing that has a hole in it that the spark plug sticks out of. Anyway I'm having trouble figuring out how to get that off. I'll try and get some pictures up tomorrow afternoon. If this is a fuel delivery problem, as alleyoop says, then what kind of thing would cause that? And are you sure that it's not just some part inside the kickstart that is shared by the electric starter that is broken? My friend who knows about motors watched the other videos, and he's still convinced that the problem is inside of the kickstart. One last thing, I can't get the cover for the kickstart off because the last bolt is shredded. Something someone suggested to me was to try welding another bolt onto that bolt and then turning it that way. How safe is that? Welding around a bunch of fuel seems bad, right? |

With the plug out it sounds different while turning over because the piston is not making compression. All of the air is rushing out of the spark plug hole.
I watched your video again and I still think it is turning over kind of slow. When you hook up the a car battery does it turn over faster?
Also, when checking for spark the tip of the plug should be grounded on the engine valve cover not the frame. The engine needs to be grounded good for spark to happen.
Once you have verified good spark and have the plug installed we can check for a fuel flow problem. Take the vacuum hose off of the nipple on the intake manifold and spry a short blast of carb cleaner in the nipple. Replace the vacuum hose and try to start the engine. If it pops or tries to run then you have a fuel flow problem and we can diagnose that.
As for the CVT cover bolt, I am not a welder. Depending on where the bolt is at I would try to get a pair of vise grips on it to break it free, or drill it and use an easy out tool.
