    Oil pump

    I am looking for help with oil pump I just transferred a 750 engine in to a slt 780 with a blown block and head so I had to put the 780 carbs and I put the 780 pump on as well but I don't know if it works 100% how much oil should be coming out there dose not seem there is much coming out.
    I would like to keep pump but looks like I may have to delete it

    how were u testing the flow rate? they pump should be variable so it wont pump very much at idle, but pumps considerably more at higher rpms.
    a good way to test is to first run pre mix fuel and the oil pump, mark the level of oil in the tank then take the machine out for a couple hours, then fill the oil tank back up and record how much it used,fill ur fuel tank up and get ur calculator out it should be some where around 50:1 mix.
