strange Tri-z carb??

[swampthang]

I'm pretty sure this is a stock Tri-z carb as far as I've see from pictures. Although I have never seen a choke lever like this on a Tri-z carb. What do you think it came from? Also I need to rebuild this carb, where can I find a rebuild kit for it? When I rebuilt my DX carb I had to use the Timberwolf kit. Is there another model thats the same as the Tri-z like a YZ maybe?

looks like someone just used a different lever on the choke that's all. i have 3 stock carbs if you need one. hell i'll let one
