So I have a Snapper bagger mower with a 6hp B&S 120000 series engine. Starts good--unless if it is hot. Then it just doesn't want to. Flooding, vapor lock, sticking valve--not sure. I just checked and it has nearly 0.015" valve clearance for both valves. Manual says 4 to 6mils intake, 4 to 8 on exhaust: but I don't think that is my problem. That said, any reason to adjust? If valve seats erode over time, then this should just close up eventually, no?
I'm guessing it just needs a carb rebuild but I was hoping for a tight valve and a fast fix there.
