Bought unit new last summer. Used it once last summer and once this year. It started fine both times. Today, it will not crank. I have replaced the spark plug, checked the air filter (it is clean), gas...
Unable to crank? Do you mean unable to start?
If you leave gasoline inside tank over long period of time, that will 'gum-up' and ruin carburetor.
To prevent problem, put additive in gasoline or empty gas from tank:: under gas tank should be a hex bolt that holds up gas filter > loosen bolt and drain gas.
Starting the engine:
Take off air filter and spray WD-40 directly into carburetor.
Start engine, engine should fire on the WD-40 accelerant.
If engine fires but does not keep running, try spraying WD-40 into carburetor continuously to see if you can keep engine going.
If engine stops each time after it no longer gets WD-40, then carburetor is bad or gasoline not getting to carburetor or gasoline is bad.
Try fresh gasoline.
Do not turn small engine on side or upside down or oil will get into carburetor.
Check gas supply: Go to gas filter under gas tank. Pull loose rubber hose that connects to carburetor and see if gas comes out rubber hose.
If gas is flowing to carburetor, then carburetor is gummed up.
Small engine repair might suggest 'gum out' or have other suggestions ... but you may need a new carburetor
If engine will not fire on WD-40
If engine will not fire on WD-40 at all, then spark coil may be bad or exhaust port is clogged
Check screen that covers exhaust >> is it covered with carbon and dirt or can air pass through it easily?
Remove spark plug
Put spark wire back on spark plug
Hold spark plug by rubber spark cap so hands don't touch metal part of spark plug
Touch spark plug threads against hole where spark plug was removed >>> metal to metal so it conducts electricity
Pull start cord and look for sparking between spark plug threads and metal of engine (don't look at the spark gap ... look where metal meets metal
If you have no spark, the spark coil is bad >> time for estimate from small engine repair shop or get your part number and order replacement
