Digital Restoration

O.S. ENGINES OS-MAX-10FSR-C

Welcome to a tour through the results of the digital restoration of this 1.76 cc glow plug engine with cylindrical cross-ribbed extreme cooling head for RC cars.

 

An engine type of the FSR 1.76 cc series, which I used during the restoration of the GO-KART-10-GP and also digitally restored. This engine type was the standard recommendation for the kart.


Single-cylinder 2-stroke engine with glow plug ignition, Schnürle flushing, rotary valve crankshaft, side exhaust, crankshaft bearing as pressed-in bronze bushing, throttle carburetor with cylindrical throttle plug. Special cylindrical extreme cooling head with cross ribbing for air cooling.
