Need a repair manual for my touring scooter - 2008 Tank Sports Urban Touring 150 Deluxe

It is Chinese junk. Promises of Service and Repair Manuals, but in reality, just Parts Diagrams! just take it to a good experienced mechanic who can fix it using 'The Force'.

Sorry I dont have a such information but however I can suggest a few general steps to take to troubleshoot and repair the issue.

1. Check for spark: Remove the spark plug and connect it to the spark plug wire. Hold the plug against a metal surface on the engine and try starting the scooter. If you see a spark, the ignition system is working properly. If there is no spark, you may need to replace the spark plug or check the ignition system for problems.
2. Check fuel and vacuum lines: Inspect the fuel and vacuum lines for any signs of damage, cracks, or leaks. Make sure they are properly connected and free from any obstructions or blockages.
3. Check the carburetor: The carburetor is responsible for mixing fuel and air to provide the engine with the proper fuel-to-air ratio. If the carburetor is dirty or clogged, it can cause a loss of power or difficulty starting. Clean or replace the carburetor if necessary.
4. Check the fuel filter: A clogged fuel filter can restrict fuel flow and cause a loss of power or difficulty starting. Check the fuel filter and replace it if necessary.
5. Check the fuel pump: If your scooter has a fuel pump, check it for proper operation. Make sure it is receiving power and is pumping fuel to the carburetor.

If you're unable to diagnose and fix the issue on your own, it may be best to take your scooter to a qualified mechanic or dealership for a proper diagnosis and repair.

Finding repair manuals with scooters is very difficult. Most
manufacturers prefer to have their dealers handle the repairs
so the dealers get the repair business. This appears to
be a Chinese made scooter, like most are these days.
Trying to get a service manual for it in China may be
more difficult unless you deal with the manufacturer directly.
Try partsproUSA as they seem to sell this model and parts for it.
