ok recently i got my old rc10gt off the shelf and cleaned the os cz12z engine and got it running. I bought a os cz12 off ebay to have as a back up, the one i got off ebay has a black cooling head and the carb dont have a low speed needle like my czz carb does, and the hole in the carb is alot smaller then my czz. anyone know what this cz with the black head is? a czr? cz2? and should the carb not have that LSN like the czz? im wondering if i should replace the carb with the one off my czz when i actully try to run this engine i got off ebay. i wanna run this engine i got off ebay so i dont put alot of wear on my czz because the czz is still like new. any and all help would be great thankyou guys.

Sounds like an aftermarket Duratrax head

in the pic looking down the carb, you can see how small the opening is, on my czz the opening is alot larger, the opening on the barrel is the same sized as the opening on the intake, where this one it is much smaller. and on the throttle arm on my czz the screw that holds the arm on is also the LSN where this cz its just a screw.

That looks like an O'donnell head...

IMO, if the carbs mounting screws are the same, I'd switch 'em...

Does it say OS on the carb?

randomhero

no it dont say os on the carb, but neither does my czz

Might be quicker and easier to swap just the throttle barrels...it would be worth checking to see if it's feasable anyway...?
