A method of reducing gaseous phase presence in the liquid fuel metering chamber of a diaphragm by providing a "High-Point Pick Up" hole positioned in the optimal metering chamber location (highest) to assure maximum purge evacuation of air and/or other gases prior to engine start-up and during running. This optimal location is dependent upon first determining, in advance of carburetor fuel feed circuitry and/or air purge system design, the orientation of the carburetor as mounted on the engine in its primary operator usage position, or so-called "standard operating position" (SOP). This SOP in turn is determined in the first instance by the engine manufacturer and/or the manufacturer of the portable engine-driven handheld appliance on which the engine is mounted. In one embodiment the two typical fluid circuits (air purge and normal idle/high speed fuel feed circuits) share a common, sole take-off inlet opening into the metering chamber, the same being located at the highest elevation point in the metering chamber in the given SOP orientation. This assures that the maximum amount of air and/or fuel vapor is removed from the metering chamber during purging prior to start-up and during running. In accordance with the invention, the primary usage position (SOP orientation) of the engine is determined and becomes a known use parameter prior to the carburetor manufacturer determining such take-off hole location. Both butterfly valve cubic carburetor and rotary valve carburetor embodiments are disclosed embodying the invention.

A portable engine driven welder is provided that has a case enclosing an internal combustion engine and a welding generator, and a running gear that is attached to the case. The running gear includes a pair of rails and a pair of leading wheels connected to the rails toward the back wall of the case. A pair of trailing wheels is connected to the rails toward the front wall of the case. The leading and trailing wheels have different resiliency values with the leading wheels being more resilient or flexible than the trailing wheels. This allows the leading wheels to act like a suspension system for the portable engine driven welder and running gear by soaking up or absorbing impacts instead of transmitting them therethrough so as to reduce exposure of the portable engine driven welder to such impacts.

An engine preheating system supports starting industrial and/or diesel engines in cold weather, eliminating the need for cold weather idling.
