    1991 seadoo sp premix

    I just recently got a 1991 sp and did a top end rebuild. I am having a problem with the injection pump. it runs good but is shooting too much oil into the cylinders and fouling the plugs. Can i remove the injection system, install a block plate and run premix 40:1? Where can i get the block off plate? any help would be awesome!!

    Your posted in the wrong place... But yes you can do that. You might even get away with 50:1, I had no issues at that.

    I realized that but am new here and cannot figure out how to delete it lol. I heard word that an adjustment to the oil pump needs to be made or does all it consist of is removing the injection pump installing the plate and mixin the fuel?
