snowblower carb screws Original Message Sep 11, 2006 5:42 pm
i have a snow tthat has a 8hp tecumseh engine and i have one screw on the bottom that i need the right adjustments for and a screw on the side that i need adjustments for.
turn screw on side, idle mixture screw, in until it lightly bottoms out. then back screw out 1 turn. screw on bottom is fuel mixture screw. same procedure but back out 2 turns. these settings should get unit started. once warmed up then fine tune both screws. at idle screw in until motors starts to die, then back out until it starts dying again. you want to be about midway. same for fuel mixture screw.. engine at high speed screw in and out.
