Halfway to work I noticed my scooter lost horsepower. Normally it'll do 30mph no problem but now it wont go over like 10-15mph. Any clue as to why this happened all of a sudden?

Your gonna have to take a look at it, or send it to a mechanic. Do you have tools? Send us a couple pics of the bike.

Its a 2017 tao tao. My scooter just has no power anymore. No acceleration. Will barely make it uphill. It'll ride fine then all of a sudden will just start to decrease in speed when driving. It idles perfect and starts right up no problem.

Likely power loss causes are overheating or fuel flow problems. Overheating can be caused by a too-lean mixture or low oil level or poor cooling air flow due to blockage or broken blower, among other things. I would take a look at fuel flow first. If you have a vacuum petcock, disconnect the fuel supply from the carburetor and place the open end in a suitable catch can. Disconnect the vacuum line from the intake, and apply suction to open the valve. Observe. If fuel flows well, full-diameter stream, then the outlet from the tank is not blocked, the diaphragm is not leaking(does the vacuum line taste like fuel or have liquid fuel in it?), the filter is working. If that all checks, the float may be sticking. If the air filter is plugged, that will also restrict power. A slipping belt can feel like a power loss, but the engine would likely be easy to rev, but you don't accelerate to match. tom

So today my belt broke while riding home from work. Could the belt possibly have been the reason for the loss of power/acceleration in my scooter these last couple weeks?

Yes it could be. If the belt was worn it would slow the scoot down then break. If the clutch or varistor wasn't operating correctly that would slow it and possibly cause the belt to break. Get a good brand name belt and open your CVT and see if anything else is wrong. There are threads in the directory telling you how to do all of this and suggesting belts to buy.

Many times a worn belt will allow the engine to go to max rpms while the scoot is fumbling along, not accelerating well, or at all. If the rpms seem to shoot up and you don't seem to be accelerating, it may be time to replace the belt. They may get 'shiny' on their side faces(of the Vee) and that indicates slippage is/has been occurring. A belt can also get thinner than normal, making it hard for the tension to be kept properly, and you get even more slippage. I would suggest Bando and Gates brand belts as being two good ones. I have not heard a lot of good things about generic, no-label belts from Far East sources. Without a name, how can a consumer decide if a brand is good or is junk? If a belt doesn't have a brand name, then they have no pride in their product. Guess what you get when you purchase products where the vendor doesn't give a hoot about quality or their product reputation. Nothing, because the product will be thrown away so quickly. I exaggerate. Some no-name belts are fine, but you have to be able to determine who is selling decent belts, and hope they keep the 'good' product line in stock... tom
