    Exclamation 1100 oil pump question!

    Ok please look at this photo and tell me if this oil pump looks like it has all the parts on it.

    The reason im asking this is because on my yamaha exciter 220 1100 motor on the oil pump it has a cable that runs from the oil pump to the carbs to adjust mixtures when giving it gas. on this motor i do not see the parts to do this and i dont want to drop this motor in unless im 100% sure the oil pump has everything it needs. I understand its better to premix. but on a boat it can become a pain in the rear!

    Google tells me that there are two types of oil injection pumps for these engines, one with a static mix ratio, and one with a variable ratio.

    Google also found me a pic of the variable ratio pump with all hoses, and cables attached. Yours could be a variable ratio, but missing some peices. Does that little silver knob on the right turn?
