Why did my moped stop running?

An intake leak really messes up the air/fuel ratio on your scooter and this can cause idling issues or worse, piston damage. On many scooters this hose or ‘boot’ deteriorates over time due to heat exposure. A faulty rubber intake hose is one of the most common cause of intake issues on scooters.

How do you fix a moped that won’t start?

If the scooter does turn over but still doesn’t start you have to check for a spark and make sure gas is getting to the engine.

Can you jumpstart a moped?

It is possible, but the electrical system in your scooter is designed to operate at a much lower amperage. Jump starting a scooter with a car will likely damage the scooter’s electronics which will lead to costly repairs. We recommend purchasing a battery trickle charger if your battery needs to recharged.

Why does my carburetor bog down when I accelerate?

There are different reasons why an engine bogs out under acceleration: The most common reason is that your air/fuel mixture is inefficient or dirty. If your air filter is clogged or has a lot of dirt. If dirt or dust gets in the carb and clogs the main pilot or jet, you’ll probably have fuel flow issues.

Should you put premium gas in a moped?

Re: Premium gas? Nope. Higher octane just means it takes more energy to ignite it. In cars (and mopeds) with higher compression, this prevents ignition via compression before the spark, better known as “knock”.
