Mike Garblik explained the power equipment factory tune setup process. "Adjust the mixture screw until it runs perfectly, then lean it out TWO TURNS!"
When fixing power equipment, I try to xref a replacement carburetor that fits and has a main mixture adjustment. It can take some time searching online parts manuals, but having it run spot on after you're done is the hot ticket. Most critical on snow blowers that are crazy lean at 70*F and are expected to run correctly at 20*F. A fixed jet carb sucks at this, pun intended.
On car carbs that I know are empty or nearly empty and the engine needs to start with little cranking (think cam break in), I put gasoline in an empty 80-90 quart bottle and use it to fill the carb up some thru the bowl vent. Its not perfect, but it will work.
