I have a fairly new Honda GCV 160 (5 HP) on a presure washer that will run for only a few seconds. I have pulled apart the carburator and cleaned it with a spray cleaner. The engine only has around two hours of use. It will start and run for only a few seconds after it has sat for about 10 minutes. It will also do the same thing after I remove the spark plug and pull the cord a couple of times. It is getting spark but it seems to be flooding. Any suggestions??
