Diagnostics Focus:
Strong emphasis on troubleshooting and diagnosing issues with detailed wiring diagrams.
Quality And Type:
High-quality diagrams, exploded pictures, and hundreds of photos and illustrations.
Displacement:
Likely 1.3L (13B) or similar early Mazda rotary displacement. Specifics would be detailed in the manual.
Rotor Housing Design:
Details on epitrochoid shape and apex seal technology.
Horsepower Range:
Typically around 110-130 HP for early 13B engines, exact figures would be in the manual.
Torque Range:
Specific torque figures would be provided in the manual, often lower than piston engines but with smoother delivery.
Carburetor:
Likely a twin-choke downdraft carburetor (e.g., Hitachi/Aisan). Manual covers adjustment and overhaul.
Fuel Type:
Unleaded gasoline (as unleaded fuel became more prevalent in the mid-70s).
Oil Consumption:
Rotary engines inherently consume some oil for lubrication of apex seals. Manual details specific oil metering.
Oil Type And Capacity:
Specific SAE viscosity grade and capacity would be listed in the manual. Likely a conventional mineral oil.
Oil Change:
Typically every 3,000-5,000 miles or 6 months. Specific interval in manual.
Spark Plug Replacement:
Intervals vary; rotary engines often use specific types and require checking/replacement as per manual.
Engine Oil Grade:
Likely SAE 10W-30 or 10W-40 mineral oil, but check manual for definitive recommendation and API service category.
Coolant:
Ethylene glycol-based coolant with a 50/50 mix with distilled water. Capacity detailed in manual.
Brake Fluid:
DOT 3 or DOT 4 brake fluid, depending on original specification. Capacity in manual.
Apex Seals:
Wear of apex seals is a common rotary engine concern. Manual provides inspection and replacement procedures.
Carburetor Tuning:
Carburetors can be sensitive to vacuum leaks and require regular adjustment for optimal performance and emissions.
Oil Consumption Management:
Proper attention to the oil injection system or pre-mix (if applicable) is crucial for apex seal longevity.
