Rare Hungarian Model Engine Moki M-7 (assembled approx. in 1988)
From the manual (excuse my English):
Tech specs:
volume - 9.95 cubic cm (0.607 cubic inches)
power - 1.6 hp at 16,700 rpm (adjustable within 2,500 - 18,000rpm)
weight - 442g (0.97lb)
This engine is powerful and reliable. Cooling is done through 3 channels (Shnuerle system),
exhaust is from the side, so a muffler can be attached, raising power to 1.9hp at 15,800rpm.
Cylinder liner is made from steel. Piston is made form alloy with low temperature expansion.
Crankshaft is made from forged chrom-nickel steel and rotates in dual roller bearings.
Adjustments on low rpm are done by needle-jet venturi and then by air regulator (changes both
amount of incoming fuel and air).
Running in should be done for 30-90 min at 12,000-16,000rpm
