FEATURES: ABL (Advanced Bi-metallic Liner) This process uses a double layer of plating material rather than one thick layer. This helps the metal bond to the cylinder and is more durable. Also, the plating process is more consistent, resulting in a more precise fit between piston and sleeve for better compression, longer life. Pilot style crankshaft Two year warranty INCLUDES: O.S. Max .12TG P engine, 12D Slide Valve Carb, #8 glow plug REQUIRES: Car Blend Fuel: 20% nitro Air Filter (OSMG2384 or OSMG2360) Electric starter and exhaust system depending on vehicle Glow starter and track equipment SPECS: Displacement: 0.128 cu in (2.1cc) Bore: 0.543" (13.8mm) Stroke: 0.551" (14.0mm) Practical RPM Range: 5000-30,000 Power Output: 0.7ps @ 28,000rpm Weight: 7.45oz (211.3g) Crankshaft Size: 1/4-28 pilot-shaft style Distance between mounting holes same side: .43" (11mm) Distance between mounting holes opposite side: 1.24" (31.4mm) Distance/top of cyl.head to bottom of mounting flange: 3.03" (77mm) Height/bottom of crankcase to top of cylinder head: 3.54" (90mm) Width between mounting flanges: 1.53" (39mm) Width of crankcase beneath mounting flanges: 1.00" (25.4mm) Exhaust outlet, outer diameter: 0.55" (14mm) Exhaust outlet, inner diameter: 0.39" (10mm) Carb inlet, outer diameter: 0.63" (16mm) COMMENTS: Some points on Slide Valve and Rotary carburetors- Rotary carbs offer a larger response in the middle of the engine's power band. This is desirable for off-road applications where throttle response must be varied. Slide Valve Carbs provide greater response at the beginning and end of the power band. This works well for on-road and racing vehicles demanding fast take-offs and high speed.
