    Default Pre mix??

    Questions ... Do you PFM guys premix? If so what ratio and what injectors do you use? I currently own the standard formula mazda prototype with the series II renesis 6 port. The oil system was deleted and I am wondering if different injectors should be used with the premix.

    Yes PFM's require pre-mix. I don't remember the ratio off the top of my head. It's approximately 5oz/gallon.
    Call Drummond Engines and ask.

    It’s 1-2 oz per gallon. Not more. I premix in the jug before fueling the car. I also got in the habit of putting the oil in the gas as soon as I filled a jug so I never had a doubt whether I had done it or not.

    Ok thank you ...
    Do you all pre-mix?
    HOW about the injectors? I have the green and brown ones but noticed they also show red and yellow injectors on the star parts site. What is the difference?
    The reason I am asking...I am having a problem , the car is stumbling between 2000-3000 rpm. It works fine if you mash the pedal, but actually stalls if you try to bring it up slowly.
