Bought Troy Built pressure Washer at garage Sale for $30.00 leaked fuel
I have a solid understanding of small engines. This pressure washer was used twice in 2013, when purchased. Sat in a garage for a couple of years with gas in tank and carburetor. Owner was moving and after 7 years of moving it around he sold it at a garage sale.
I took it home and took off gas tank and thoroughly cleaned it. Then we ... Read more nt through the carburetor and let soak in cleaner. Cleaned up the spark plug, tested and has good spark. reinstalled carburetor but would not start. I knew I had gas issues. I ordered a carburetor kit and replace the needle valve and seals. Still would not start. Ordered a new carburetor and spark plug. Installed both. Two pulls and it runs like new. Advice: don't try to clean out old carburetor, just buy a new one and install.

Everything went just as planned...….well except the two bolts that where included by Briggs and Stratton appear to be 1/8-1/4" too short and now both of the threaded holes in the engine are now stripped and the quick

easy repair is now a bust and not repairable by me.
This has nothing to do with PartSelect.com as they just shipped the Briggs and Stratton part box.
