I have a husqvarna model YTH 2348 lawn tractor with a Briggs 23 hp INTEK engine.
It ran fine at last use and one week later when started it was popping back thur the carb on one cyl. It has 160 # compression on both cyl,s.(It does not pop when both spark plugs are removed) It has good spark. It will run but only on one cyl.
Any idea?
