Abstract
A handheld combustion powered fastening tool may include a driving system that drives fasteners into workpieces in response to combustion of fuel by the driving system. A fuel delivery system may supply fuel to the driving system. The fuel delivery system may include a fuel canister storing liquid fuel, such as liquid hydrocarbons such as propane, and a fuel metering valve supplying a previously set amount, or volume, of fuel from the fuel canister to the driving system for combustion.
