1989 Scooter will not start  By  kxj5906 (Read 727 times)

Well did it used to run ? Remove the sparkplug , stick it back into the boot ( the wire ) make sure to lay the tip against the engine or frame so its grounded and hit the starter button to see if it fires . Spark will be weak since the starter does not spin as fast as the engine does when it is running . Yes all have a safety switch that requires a brake lever to be pulled in in order for the starter to work . Even back in the 80s my Honda mopeds I had to do that . If the brake light switch goes out you would have to use the other lever until you replaced the switch if it went out .

Does it have compression ? Quick simple test is to push down the kickstarter by hand to get a rough idea . Harbor Freight has a compression tester with a gauge that reads in PSI for 20 dollars .

I have gotten bad gas and it caused my perfectly running scooter to not start the next day after getting bad gas . I bought a manual siphon pump for 5 bucks to drain the tank and drained the bowl on the carb with the drain plug removed . Poured if gas from a trusted source and tada it was new again . I was out doing a long ride in the country and I was too far out to chance it to one of my gas sources .

Here is a valve adjustment guide www.scooterforumonline.com/index.php/topic,1720.0.html All 4Ts will need it done at least once with some needing it out of the crate . Any auto parts store you can get a valve feeler gauge for 3 dollars . These have the tip bent so it fits in there where standard feeler gauges are flat blades .

I bought the Haynes Chinese Scooter repair manual from Amazon for 6 dollars since it was used . Generally its 25 on the average new there or from one of the sponsors here

Could be a 2 stroke Vespa too. What is the make and model of the scooter. Some of the 2 strokes have a sensor on the oil injector tank that will also prevent them from running if the oil level gets too low.
