I, starting my fourth round of rebuilds on my 121 rojo.

My car (a B18A engine) has only one carburettor (ZS175) and it is matched with a "C" camshaft.

The engine has a cronic tendence to overich the mix (too lean, idle stops, but if idle ok, too rich on the upper side = black smoker at 100 kph).

Carb was rebuilted 2 years ago, and at low speeds(less of 60 kph) it works flawless.

If some another member has a similar configuration (probably on use in Europe), please, I need some info for comparisions: usual idle sped, valve spacing, usual timing (my specs was for the original A camshaft, and it don't work too good with the C cam).

Also, I need some info about if the C cam is a overkill for one carb (possible?). If that is the case, theb probably I will be need to jump to 2 carbs setup, or downsize to a A cam.

Thanks in advance for your answers,

Joaquin (yogui the bear) / Rojo 121 / Lima, Peru
