husqvarna yth2448 lost compression


Mower running well. Died and would not start. No compression at all. Thought flywheel was not turning engine, but checked spark plugs and it's firing, but no compression. Any ideas.

Could be a bent or stuck valve.

How old is your mower? Is it a Briggs & Stratton engine? The older Briggs 24 hp twins had a few design problems. First was the air cleaner. It would seal when new but eventually, with age, allow dirt to bypass the filter. Second was a problem with the oiling system. On hilly terrain one of the connecting rods would starve of oil causing it to break. Both those would mean it's time to replace the engine or mower however, it could also be a valve issue that you can fix, see this video to help.
