Thanks heaps guys! I got my new exhaust made up - Involvolving 1/2" water pipe, a step up a 3/4" and a 3/4 5hp muffler. I like those on small block engines - gives them a deeper sound and they run quiet!
Cannot wait to start my next project. I am nearly finished overhauling my 1974 tru Test, and will then be starting on another. This one is original, with a reel mower 1969 2HP Briggs, max torque clutch, 60t #35 sprocket...:thumbsup: Was thinking of powdercoating it metallic orange!
