Reeds with a lot of porting in that cylinder. Castings were crappy compared to the Italian engines. I had one of the very first LMR's off the line. Dan Lumello was at APPCO in those days, and he personally modified my LMR. I took the HR off and replaced it with an alky Mikuni. I also made a manifold plate so I could use two HL293A Hartman blueprinted carbs for short tracks. The engine was truly a rocket, but it was very unreliable. Mr. Lumello eyebrowed the exhaust port a bit wide, and the Dykes ring tended to hook on the edge. When that happened, usually at top RPM, it would rip the top ring land off the piston and pound the pieces of the ring into the head. I went through about five pistons and heads. It was fast as lightning when it ran! I had George Pollock build me an open Atlas as soon as they came out. It was fast, but never as fast as that LMR! If it had had a driver better than me, it'd have been unbeatable. Someday I need to get the pix of my '75 Wasp/LMR scanned. Ted
