OS 12CV-R W-10E Off Road Carb
The latest 12CV-R is a lesson in how to extract maximum performance from a small, compact package. A larger crankshaft gas passage and optimised port timings create the impressive power. Max 12CV-R (P) allows fitment to cars that require the 'Plain' style crankshaft and also uses the 10A slide carburettor. Only the 12CV-R is supplied with a drive washer.
