Dual Fuel Carburetor - create a cutting guide
[21] Cut a section of 1 1/2" thinwall sink drain to about 3 1/2" in length (you can use either a straight or an elbow fitting, depending on where your wood-gas feed hose enters the engine compartment), then slip it into the opening and mark a cutting line on both its sides, using the carburetor's walls as a guide.
