Thread: Can the fuel bowls on a 4150 be reversed?

  1. #21


    I was able to use a screwdriver bit on a quarter inch wrench and back the secondary screw off. Maybe three quarters to a full turn. I opened up the primary idle screw and reset it to two turns on the mixer screws. After starting it I had to turn out the screws to about two and a half turns and it came down to about 14 to 1. So tomorrow I'll try and back it off a little bit more.

    Just make sure you don't back the secondary off beyond sitting on the stop screw. They should be open at least 1/4 turn past contacting the lever.

    OK, thanks. Hopefully this weekend I can take it for another drive.
