Agility 50 / Re: Air filter smells like gas

This is very common in 2-stroke engines as there is nothing stopping unburned fuel from coming back out through the throat of the carburetor.  From what I've seen in taking apart the Agility 50 carburetor, I wouldn't worry about it.

Agility 50 / Re: 2009 Agility 50 - Carburetor Issues

Rianna,

Thank you for your post.  Is there anything listed in your manual regarding adjusting the idle mixture on the carburetor?  I've check all diaphragms on the carb and they look fine.  The scooter has about 400 km on the clock.  What boggles my mind is how the engine can idle and somewhat accelerate, which tells me that the idle jet is working fine and there are no air leaks, however, after it reaches a certain rpm range, it just quits.  If I open and close the throttle quickly, I can get the engine to run past the "problem rpm" range and reach full throttle speeds, but it takes some finesse.

I've installed a 55 micron fuel-filter thinking it would stop these carb problems, but it has not.

SO FRUSTRATED!

Rianna,

Thank you for your reply.

I believe the ignition system is working properly on the bike.  The way the engine quits at a certain RPM range tells me that it's fuel-related. 

What is the air cut-off valve you mentioned?

Agility 50 / 2009 Agility 50 - Carburetor Issues
« on: December 02, 2010, 08:04:49 PM »
I have a 2009 Kymco Agility 50 that is currently experiencing some suspected carburetor issues.  I have cleaned the carb jets as well as all passageways through the carburetor and the problem still exists.  The problem I am experiencing is that the engine will stumble and stall when running at about 1/4 throttle.  This could normally be adjusted with the idle mixture screw but the mixture screw on this carburetor has a tamper-proof screw installed (as opposed to the standard flat-blade screw).  I would imagine there is a special tool that will connect with this tamper-proof screw, but so far I have been unsuccessful in finding such a tool.

I have checked all vacuum lines and have no leaks anywhere on the engine.  I am very mechanically-inclined and am stumped on this one!  I'd greatly appreciate the assistance of some real Kymco experts :)
