1. A method of operating a fastener-driving tool including a housing, a combustion cylinder supported by the housing and defining a combustion chamber, a fuel assembly supported by the housing, and a canister mounting subassembly connected to the housing by at least one mounting element, the canister mounting subassembly including a fuel canister mounting carriage, the method comprising:
receiving, by the fuel canister mounting carriage, a fuel canister such that the fuel canister:
is within a plurality of spaced-apart pairs of canister-retainer fingers of the fuel canister mounting carriage;
engages longitudinally extending ribs of the fuel canister mounting carriage, and
is partially within a fuel canister closure engager of the fuel canister mounting carriage; and
thereafter, causing the fuel canister mounting carriage to move from a rest position to a dispense position.
