Title: 2013 Kymco Agility125 will start but won't stay running
Post by: mdeckeradpro on February 18, 2020, 04:27:02 PM: I got a 2013 Kymco Agility125 from my mom that had been sitting for a couple years. I drained fuel system, put in new battery, etc. After I refilled it with fuel, I put some injector cleaner in the tank with new fuel. I can get it to fire and run for a few seconds, but it just dies like someone is cutting it off. I did get it to idle for about 30 seconds last night but couldn't repeat that. Any ideas? Fuel system blockage? What am I missing?

Thanks,
Marc

Fuel cleaner will not work if the passage is blocked where it can't flow through.

I think chances are very slim that an injector cleaner will be able to clean a clogged injector within 30 seconds.
You should replace the fuel filter and if the injector can’t be cleaned, you probably have to buy a new injector.

P.S. you mentioned “injector cleaner” so I asume you Agility came with a EFI system - not a carburetor.

I had to look it up in my prior post to know it was carburetor model not fuel injection.

Be worthwhile to purchase a service manual from Cyclepedia.com, or other, for this scooter. Saves a lot of guesswork. @$30> $40. Some can be found online...but I like the clarity of the cyclepedia manuals.

My Agility has an in-line fuel filter between the fuel tank an the carburetor. At the left, (CVT side) side, higher up towards the seat. 2013 model as well. If you can’t find a filter between the tank and carburetor I guess the filter might be inside the tank.

Mine is at the same place.
