Pilot jets for Carburettors

How To Make Precision Pilot Jets

Everyone knows how sensitive an engine is to pilot jets in the acceleration stages from 1000 to 3500 rpm and getting fuel mixture right in this area is critical. For this reason jets have be perfectly accurate in their marked size and incremental size steps. This year EBC Brakes sister company A-BAX Precision Engineering Ltd in the UK has purchased the most accurate machine on the planet for this work shown below. A-BAX Precision Engineering Ltd pilot jets are precise, clearly marked and reliably gauged using pin gauges, accurate to one tenth of a thousandth of an inch, you can rely on their accuracy.
