I have a pressure washer with a 4 horse Briggs and last night I had it running last night and was having trouble with the garden hose leaking underneath where the water pump is mounted so I shut it off and tipped it up to work on it and it wouldn't start after that. I let it set overnight thinking it was just flooded. It wouldn't start again today so I pulled the plug and their is no spark. So I tried a new plug and no go. I took the shroud and cover off the engine clear down to the flywheel and everything was clean, no oil or gas or anything had leaked onto the magneto or flywheel. So I thought the magneto had gone bad. I have a 4 HP lawn mower so I tested the magneto and plug on it first and it had great spark. I took that magneto and plug and put on the pressure washer and still no spark. I cleaned and sanded the flywheel good after that too and still no spark. This washer is just slightly over a year old and has been used little. What else could be wrong that would stop it from sparking??
