STA-BIL Fast Fix Small Engine Treatment, 8 oz
The eight-ounce Fast Fix exists because small-engine trouble rarely travels alone: the mower that sat all winter usually parked next to a trimmer that sat all winter.
It carries the same concentrated cleanup as the small bottle with enough volume to treat the second machine — or to give one badly varnished carb a follow-up round.

For the shed where nothing wants to start.
Two rescues per bottle
Treat a pair of neglected machines, or double-dose the worst one.
Deep-clean chemistry
Built for gum and varnish, the stuff that chokes jets and sticks floats.
Run-through repair
Pour into fresh fuel and let the engine do the cleaning as it runs.
Shed staple
The bottle that turns 'it won't start' from a crisis into a procedure.
