I have a 4 year old Husqvarna walk-behind with a B&S 175cc engine (111P02-0116-F1). engine wouldn't start - started trouble shooting and found that when the breather tube was disconnected from the air-filter housing the engine would run. With engine running, i would ease the breather tube back into the air-filter housing and the engine would quit. No oil seems to be coming out of breather, but perhaps there is some exhaust coming through that is starving the engine? i did see some wisps of white smoke coming from the breather tube, but almost to thin to see. Engine also backfires through exhaust pipe when engine shuts down. Any ideas?
thank you!
