I have a two year old Troy Bilt pressure washer with a GCV 190 Honda engine. The pressure washer has worked fine for two years (although I have rarely used it).
Recently, I broke out the pressure washer to use for the summer, and I ran into an issue. The washer ran fine for about the first hour of use, but then it shot black smoke from the exhaust and cut off. I could not get the washer to restart.
I removed the spark plug from the washer, and it was charred almost completely black on the end. I bought a replacement spark plug and installed it. The next day when trying to use the washer, it would run but the engine sounded like it was struggling to stay on, and whenever I turned off the sprayer the engine would die. After about an hour, more black smoke came form the exhaust and the pressure washer will not crank again.
Does anyone have an idea of what the issue may be? I've put new gas in the engine and the oil levels look fine.
