Fuel contaminated carburetor

Screwdriver, Pliers, Carb cleaner
I was certain cleaning the old carb parts was all that would be required to get the snowblower to run again. After soaking old parts in carb cleaner and reassembling old parts. The snowblower wouldn’t even try to run. New jet, with new Orings, new needle valve and seat, new bowl nut and gasket were parts installed to finally get the motor to run. I’m uncertain which part was the culprit, but it runs fine now.

Just removed 2 screws to bottom plate. I unplugged wires to switch. Pushed in on both sides of switch and pushed up out of top plate. Pushed in new switch and connected wires to it. Replaced bottom plate with 2 screws. Turned on switch. Pushed primer button and put on choke. Pushed electric start button and it fired right up. Let it run for a minute and turned key off and it stopped running. Problem solved.
