I spent in excess of $600 rebuilding fuel systems on small two-cycle engines until I switched to non-ethanol fuel. Since, not one dime, and everything cranks on the first pull. This is nothing but cram-it-down-your-throat, ‘we know best’, govt. BS! Enough of this crap!
I broke down and bought a 4-cycle engine for the weed eater hoping that will help.
I live in the area that requires reformulated fuel, no non-ethanol gasoline available.
I’ve had a few 2-cycles to rebuild carburetor systems on also. I made the mistake of leaving the gas in my Mantis for over a year, and the damned gasket on the gas cap completely melted and flowed into the carburetor when I tried to start it...had to make all new gaskets, new tubes, carburetor rebuild kits - the works. This government sucks.
I didn’t spend more than 10 bucks and got my all my small engine problems fixed. Try Amzoil Quickshot for small engines, and PI for your vehicles.
