They have generic Service manuals but that does not help in diagnosing what is wrong with them. They just tell you the specks on this and that. You will not find how to check for fuel delivery and how to eliminate this or that by testing or how to check for spark or how to adjust your carb nothing that will help you find what is wrong when something happens that causes the motor not to run right. I just find them useful to find out where the tabs might be on the panels and screws holding them on etc..
Also many scooter shops just replace parts until they finally replace the part that is actually bad. Most shops I find do not know how to Diagnose a problem they just replace and you get a big bill and new parts you did not need. Don't forget they do not make money on selling scoots they make their money in the back room. To keep the business going and paying workers they would have to sell quite a few scoots a month or weekly and hundreds in a year. Just like the car dealers they do not sell hundreds of cars a month they make their money in repairs that is what keeps them going.

Alley I agree 100% about shops. Thats why I don't want to give up, but it gets frustrating. ..

Will find it, just that the main problem was the hoses they were ripped and old. The main one was the short Vacuum hose coming off the intake manifold. Right now we are at the finish line, you say it has spark valves are adjusted good vacuum hoses. So now there are only a couple of things left.
1. Fuel pump (gas delivery)
2. Clogged Pilot jet and or passage(gas delivery)
3. Compression(OUCH)
That is it that keeps the motor from starting.

Yea that is why I put it there(HAHA), that means a re-build rings or valves are shot. We can test that as well if it has descent compression. How you do that if you do not have a compression gauge is this way:
1.You take the plug out .
2. Stick your finger in the plug hole nice and snug.
3. Hold the throttle wide open so it sucks in as much air as possible.
4. Crank the motor over.
5. IF IT LIFTS your finger OFF the hole it has descent compression.
6. If you just feel some pressure on the finger then NOT GOOD and the motor will not run.

Sounds good It is either no gas, no spark or low on compression.
So test the fuel delivery.
Take the fuel hose OFF the carb and stick it in a cup and do the same thing crank it and see if fuel comes out in good amount. If it does that means the fuel pump is working.
Then put the hose back on the fuel carb connector and then OPEN the Drain screw on the bottom of the CARB next to the DRAIN HOSE and Put a CUP or PAN something to catch the fuel then do the same thing crank the motor and fuel should keep on coming out of the drain hose.
IF IT DOES then we know fuel is being fed to the carb.
Get back on those tests

That hose that you say is LOOSE where on the motor is it attached to? It could be the HOSE ATTACHED to the connector on the VALVE COVER like this:  |

Going to be leaving at 3:30 central time for Chow with friends will be back around 5:00ish. But if bad good or bad delivery of gas from the pump then do this: Take that SHORT hose going to the BLACK "T" off get about a teaspoon of gas in your baster or squeeze a cup to a point and pour the little bit of gas down that hose. RECONNECT the VACUUM hose to the "T" and try to start it. IF it is getting spark it should attempt to start or at least fire once. If it does fire then we know it is a GAS PROBLEM and if the pump is good then it is time to clean the carb. Alleyoop CLICK ON THE PICTURE TO EXPAND IT BIGGER SO YOU CAN SEE THINGS BETTER.  |

Both of the hoses that are lose came off of the white T I use to have. One hose is coming off of the side of the gas tank & the other hose is coming from the bottom of the engine..
