Thanks Bruce, I will get the info on the B & S when I go up bush.
Thought you might be interested, I have been playing around with the Suzuki s200 water pump today, and it appears that the position of the choke affects the smooth running i.e. if the choke is not opened up completely the motor runs a lot smoother (even when hot). I will know more when I test it at the [Censored] tomorrow. I have stripped and cleaned the carby, jets and tank.
