Got spark? First check for spark. There are a few ways to do this. The easiest way is to remove the spark plug and put it back in the spark plug cap. Then ground it to the engine - you should be able to lay it against a non-painted portion of the engine. Make sure there is good metal-to-metal contact. In a semi darkened area, attempt to start the scooter. You should see a definite spark at the tip of the spark plug. It's hard to see in direct light. If the color of the spark is blue, that means it's a strong spark. A white color is less strong, and a yellow color is weak. Most scooter starting systems are a bit weak (compared to cars). Even a yellow spark should start your scooter just fine. Next, the spark must occur at the right time. Just about all scooters made since around 1980 have electonic ignition. These systems rarely can be set. This is good news. After working on maybe 50 scooters, I've never seen one go out of time. Scooters with points are another matter. You'll have to follow the timing procedure in the manual to get the timing correct. In general, the spark occurs just before the piston reaches the top of it's stroke. There is a slight delay between the spark plug fire and the fuel-air mixture ignition. That's why the spark occurs a little early. Most ignition systems have an advance unit build in, so that as the engine speeds up the time of the spark retards a little bit and helps the engine fire the mixture at the proper time.

Compression check. If you just acquired the scooter, you should first do a full inspection before you try to get it running. Please see this page on restoration. If this is the case, I'd do a compression check first because it's easy. First check the quantity and condition of the engine oil. Add oil as necessary. I wouldn't change it unless it's terribly dirty. The engine could be bad so you'd waste the oil change. Hook up or purchase a good battery. Leave out the spark plug and crank the scooter for ~5 seconds. This helps to circulate the oil. Let it set for ~15 seconds and do it again. It's not a good idea to continuously crank the starter because it can overheat and wear prematurely. Most scooters need a minimum of 100 psi in compression to run start and properly. Compression should be checked when the engine is warm, but that's kind of hard to do if the scooter is not running. So just hook up a compression gauge and open up the throttle all the way. Crank the scooter until the needle on the compression gague stops moving. This should take no more than 5 seconds. Very roughly, 100-125 psi is good, 125-150 psi is very good, and 150+ psi is great. If you don't have this level of compression then you have bad valves and/or bad piston rings. If you want, you can add a teaspoon or so of oil to the engine through the spark plug hole. Then try the compression test again. If compression is higher, then it's likely you have bad rings. The oil will seal the rings and give you better compression. If compression is the same, then you have bad/misadjusted valves.

Remove the fuel and vacuum lines that run from the petcock to the carb. Place a suitable container under the fuel line and draw air on the vacuum line to the petcock (if so equipped) and see how well the gas flows. The flow has to be more than a trickle. It should be steady and fairly substantial. If you get this flow, then you're ok.

What changes to I need for high altitude? This doesn't come up very often, but I though I'd throw it in anyway. At high altitudes (above ~4000 ft), your scooter will start starving for air. You'll need to place a smaller main jet in the carb, so that it will take in less fuel. A good rule of thumb is to reduce the size of the main jet by ~10% and see if that works.

My Idle Runs Too High. This could be due to a throttle cable that is too tight or misrouted. It could also mean you need to turn the idle screw on the carb counterclockwise 1/4 turn. A high idle may be due to a vacuum leak. The rubber manifold between the carb and the cylinder head can crack over time. Try starting the engine and squirting some water around the carb, manifold, and vacuum hoses. If the idle decreases, you have a vacuum leak somewhere.
