Hi Debbie,

Most problems with gasoline powered equipment are related to the carburetor. This happens frequently if this equipment is not stored for the "off season" properly. Fuel remaining in the equipment can form varnish that will interfere with movement of carburetor's internal parts, clog the tiny orifices, etc. Often, disassembly and through cleaning with solvents and clearing clogs will return the engine to good running order with little to no need for replacement parts. Making adjustments to the screws and springs on the carburetor is looking for trouble - don't do it. The carburetor is a simple device - but has some pretty small parts that are easily lost of you're not expecting them to fall out during disassembly. Your best bet is to have the mower serviced by a pro. If cleaning is all that is required, it shouldn't cost more than $50 - $75.

You can save yourself this headache next year by either running the engine until it is out of fuel - or removing any fuel from the tank and then run the engine until all remaining fuel in the lines and carburetor has been used completely. This is a good time for an oil change and maybe even a new spark plug. If you didn't do it last year, you might want to have the pro do it for you when he works on the carburetor.

Good luck!

My throttle position markings have worn off. Is start position to the front or rear? It cranks in both but quickly dies.

Usually if you push the lever forward that is the start position (or choke position) once started in this position from cold start, slide back this should be fast, slide a little further back and this should be slow then all the back should stop. Have not worked on a lawn boy silver for about two years now but all are about the same, anyhow give that a go, good luck!

Lawn mower chugging

better late than never, I have the same mower

there is no throttle control on these mowers, if you look under the air filter the throttle is balanced by a spring pulling in one direction and a lever controlled by engine speed. if the spring breaks or falls off the lever will wiggle back and forth, more gas if the engine slows, less if it speeds up. you end up going fast/slow/fast/slow etc.

The tension spring slows the switching down and smooths out the engine speed.
