I have this old Craftsman mini tiller/cultivator aka POS, I'm trying to get running again. Need it for my garden. It will start, but then dies. Classic symptom of the carb needing adjusted. I've replaced the fuel lines, primer bulb, ect. Spark plug is good, gap is good. The problem I'm having is the mixture adjustment screws (H,L) do not seem to be spline, like all my other engines. I have a spline/carb adjustment set of 6 drivers, none fit. They appear to be spent shell primers, you know, having a little dent in them.
I'm attaching a photo of the mixture screws. Can someone tell me what tool is needed to adjust them? Also attaching photo of the POS tiller, and only engine info I can find.
