Hi all
I have a pressure washer from Northern Tool..Honda GX 160 engine 5.5 HP / Comet pump that is about 3 years old. Bought new / used several hours per season and always well maintained.
Always runs fresh fuel / 90 octane...run carb empty when done, etc. New plug every season.
It starts great, runs strong but has an annoying backfire when you let off the pressure wand. Doesn't do it everytime. I adjusted the valves last year and it seemed to help, but it still backfires some.
Any suggestions on what to look for?
