Why will my moped start but not run?
Check the Engine Ignition and Fuel System: In most cases, the problem with a scooter not starting but with power is caused by an issue with the engine; either a bad spark plug wire, bad plug or a fuel system problem. This is caused by a problem with the spark plug, spark plug wires, or the ignition coil.
How do you prime a carburetor on a scooter?
To ‘prime the carb’ is to basically manually fill the float bowl. It takes a lot of vacuum to suck fuel thru dry fuel lines. So you want to connect a piece of hose to the carb fuel inlet nipple, then a funnel or something to the other end of the hose and manual fill the carb float bowl with fuel…
What should I do when my moped wont start?
When the engine is cranked over, you should feel your hand being sucked into the carb. It should also get wet with fuel. This will force choke the engine, and after doing this for a few cranks, the engine will draw fuel into itself. Then hold the throttle wide open, and crank again, to see if you get a “pop”.
What do you need to start a moped engine?
All moped engines operate on the same principles. Every engine needs Compression, good fuel, and good spark to run. If your machine has been sitting for a long time, there are a few things you should check out before trying to start the engine. 1. Check to see that the engine turns over, and has compression.
How do you know if your moped is running?
Crank the engine over, and it should have enough compression to “pop” your finger off the hole. 2. With the plug attached to the coil wire, lay the plug against the block so that it is grounded. Turn the engine over with the kill switch on, and you should see a bright blue spark between the electrodes on the spark plug. 3. Look in the fuel tank.
How do you know if a moped engine is plugged?
Turn the engine over while holding your hand about 2-3″ from the exhaust tip. You should be able to feel air pressure coming out of the muffler every time the engine turns over, proving that the exhaust pipe is not plugged. 5. Set the choke and turn the engine over. After several cranks, the engine should start, or at least start to “pop”.

What should I do if my moped turns off?
If it turns, make sure the kill switch is “off” so you do not get a shock from the coil wire, and put your finger over the spark plug hole firmly enough to get a good seal. Crank the engine over, and it should have enough compression to “pop” your finger off the hole.
