Title: Agility Carb same design as?
Post by: eamartin on January 02, 2019, 01:25:16 PM

My 2011 Agility 50 carb needs help.  Is this CVK carb a copy of a Keihin model?

Hi,

Isn't CVK a common brand in itself?

Is it a 2T or 4T bike?

A little research seems to indicate that CVK is a type of carb designed by Keihin.  The Agility carb has no Keihin name on it - only Kymco and some letters/numbers.   If things go sideways on this I may need a new pilot jet and was hoping the Keihin jets would fit.  4T, by the way.

Ahh - for the 4T motors a lot of the carb parts are pretty similar and I'm fairly sure that, if you had the pilot jet out and checked the numbers/measurements, you'd be able to get a pilot jet :)

The jet is damaged.  One of the jet tabs is broken off so I cannot get a flat blade screwdriver to work.  Also the tab must be the one with the size# stamp on it but I'll assume it's a 35.  Also the jet is clogged/blocked.  I'll first try to clean out the jet in place. The jet head is recessed so I'm not sure if a jet drill bit will reach it.  I'll find out later today.  Thanks.

Good luck, and let us know how you get on!

I was out of town for 4 days but before leaving I turned the carb over and filled the recessed area to the pilot jet with dip cleaner for carbs.  Upon my return I was able to get a tapered broach through the jet.  Then, after filling the recessed area with WD-40, I could blow the WD-40 through the passage with compressed air.  I repeated this step once.  Then I filled the recessed area with throttle body cleaner and blew it through the passage with compressed air.  Since I don't know if the open jet orifice is cleaned thoroughly, I'll get a properly sized jet drill to run through there.  I still will not be certain that the remainder of the passage is sufficiently unobstructed.  After that, it goes into the magic ultrasonic cleaner. At that point, since I know that the pilot fuel circuit is at least somewhat open,  I'll be willing to install the carb and see what happens.
