Working on another Craftsman lawnmower 917-388660 briggs. 123K02-0258-E1. The guy bought it used from someone else, the primer bulb was leaking. I took carb apart, fuel of bad fuel and water, not salvageable, replaced carb. Cannot seem to get the primer bulb to work. Took off primer base, blew a little air through the primer hole on the carb, it squirted fuel. Using new carb gaskets, even tried brand new primer base and it wouldn't prime either! On the original primer base, took out primer and cleaned it really good, made sure the hole was clear, replaced with new primer bulb...still nothing! I know this has been talked about a bunch...seems like they work or they don't!
