My John Deere D160 with a B&S 44S977-0001G1 engine surges constantly unless choked at a precise amount. Pouring gas into carb makes it run smooth(er) until the excess gas is used up and then it surges again.
I changed fuel filter, checked fuel lines for kinks and then I removed the carb, cleaned the bowl which had some crusty stuff in it, and spray carb cleaner in a few holes and in the float needle, etc. Same problem. I guess this is a carb rebuild. Before I do that though, how can I check fuel pump for adequate output? What else might I check?
