Is it worth running a bit of that car fuel system cleaner stuff through a 4-stroke lawn mower to clean the carburetor and such?
Since my 4-stroke lawn mower has been running for 15+ years (It's a Briggs & Stratton) i think it might be a good idea to do a big service on it aka
new piston rings,throttle cable,oil change, and spark plug change.
The carburettor on your Briggs and Stratton should not really require cleaning, assuming that the air/dust filter has been kept clean(by soaking it in
petrol overnight),if the filter is either dirty or clogged the engine would be difficult to start anyway.
Before you undertake a major overhaul, check the compression in the engine, simply by removing the air filter and placing the palm of your hand
against the carburettor intake, if there is sufficient suction to enable you to feel your palm being sucked with enough suction to cause the engine to
cut out,it should be ok.a very small amount of Redex added to the petrol before each use should ensure that carbon deposits are burned off.
No i have not waited 15 years to do an oil change it's just i've noticed there's a bit more smoke than usual upon starting it from cold and the
throttle doesn't seem as responsive then i looked at the throttle cable and noticed it has gotten bent and that's likely the reason why the throttle
dosn't seem as responsive.
It's likely been awhile since the mower's air filter was last cleaned.But my Morrison rotary hoe is in even worse condition than my mower it hasn't
had an oil change or new spark plug for years plus the petrol/gasoline just sits in the tank since it hardly gets used but once i get it started and
tune it,it runs just fine.
