Time: 1 hour (approximately)
Tools: socket set, flat-blade screwdriver, small putty knife or scraper, adjustable wrenches (optional).
Cost: (varied) approximately $100-$300
Tinware: center-hung float fuel bowls (if needed), metering block and hardware (sold as kit), metering jets, replacement gaskets, dual-inlet fuel line.
Tip: transfer the carburetor from the engine to a clean, open workbench. If you don’t have a carb stand, simply slide four bolts of your choice through the mounting holes in the bottom plate, and “nut” them up at the top. All you need is enough clearance for the levers and protruding linkage. (see photo #1)
Performance gains: increased fuel delivery and tuning accuracy.
