Hey guys I was wondering if anyone has changed the carburettor on a 21r motor besides a 32/36weber etc.

I know they're pooey engines but i like to get the most out of my cars. There seems to be information on 20r and 22r but not so much on a 21r.

Does anyone know if the 21r uses the same carb as a 22r or if its a viable/cheap upgrade, or anyone that has sucess with using a carb off another car with modifications.

Im all for effort and minimal cost so any quirky carb swaps to these 2XR motors im all ears.

Cheers
Patrick
