@prodigious08 We're talking Chain Saws & other tools using the Walbro Carb....Not "Cars" with "gas pedals". (The Video is very clear:& Well done.)

When you apply "gas" via a trigger or pedal, you admit more air to the engine, which, thanks to the design, pulls more fuel into the airstream, hopefully, at the right proportions. This pulling of fuel in proportion is the "Venturi principle"....all carbs use this, with various modifications, to improve performance or economy. The Walbro is a classic!

Wikeroy, You went to a lot of trouble to explain the Walbro. I made the mistake of ripping into disassembly, without noting carefully gasket location and screw lengths. nest time I checked and noted component location. Thank you great presentation
