Pinch off the fuel line with a pair of vise grips. Drop the float bowl (be sure to note the position of any drain plugs or flat sides of the bowl) by loosening the bolt in the center. Be sure not to loose the gasket.
Carefully slide out the pin that the float pivots on and remove the float and needle valve that is attached to it. Give them a good wash of carb cleaner. Give the needle seat and main jet a good blast of carb cleaner. Reassemble, being sure not to pinch the gasket.
Take off the vise grips to let the float bowl fill with fuel. You're going to have to pull the rope several times to get fuel moving through the carb. Hopefully, it will run properly now.
Next winter, let the machine run until it is out of gas and dies, so you won't have this problem again.
Put fresh gas and a spark plug in. Use starting fluid and keep the nozzle open to relieve water pressure. Mine takes at least a dozen starts at the beginning of the year to run on it's own.
Stuck float, gummed up float valve, dirty idle jet, you are going to have to get into the carb and clean up the jets other parts sitting too long is a problem unless the unti was run until empty of fuel or the carbs run until dry.
drain the old gas . change spark plug if new gas doesn't do it . Clean out carburetor with spray cleaner if ypu can . Gas gums up after sitting
Take the bowl off of the carburetor and clean the jets, also change the fuel filter.
My dad and I have a pressure washer that worked fine last it was used, but that was about a year or two ago, now it will start for a few seconds and then sputter out.
We have changed the spark plug, changed the oil, filled it up with new gas, checked the air filter, but it still will not stay going, it just runs for a couple of seconds and then dies off.
What could be causing it to not start? Its a TroyBilt, or however it is spelled.
