Power washer with a GC190 would not run. Changed spark plug, ran for an hour, turned it off, next day, will not start. Not sure if getting spark, plug still good, oil and fuel good, any recommendations?
Fuel, air, and spark at the right mixture and time, and it should start and run. Has it been sitting? Check the oil? Some small engines these days will not run with a low oil level. This is a good thing.
