AMAL PILOT (BUSH) JET DRILL #78 .016
A #78 (.016 in.) pilot jet drill sized for cleaning or resizing Amal carburetor pilot jets.
This is a drill sized specifically for cleaning or resizing the pilot jet passage on an Amal carburetor. It's a #78 bit at .016 in. diameter, sized to match the small pilot jet drillings Amal uses rather than a standard machinist's drill index size. If you're rebuilding or fine-tuning an Amal carb and need to clear a clogged pilot circuit or open up a jet by a known increment, this is the tool for the job.
