We recently completed a tidy 12A Bridgeport engine that showcases precision engineering and attention to detail. The build used 13B JC housings machined down to 12A specifications, while 13B FD stator gears were cut down to suit perfectly.
The result is a compact, reliable, and well-sorted 12A engine with all the high-quality components needed for strong performance and long-term durability. A perfect example of building small, tidy, and powerful rotary engines.
