My pressure washer with a Briggs engine won't start today. I ran it last week until it ran out of gas. Two days later I tipped it over to drain the old oil out, and yesterday I put fresh oil and gas in it. I have wet fuel at the plug, I can see the spark, and I have air too. I tried a shot of starting fluid into the carb, and later into the plug hole. I think I will pull the carb, clean it out and reinstall it.
