Brake Fluid Type:
DOT 3 or DOT 4 hydraulic brake fluid. Manual will specify precise requirement.
Rotary Engine Wear:
Apex seal wear, oil seal failure leading to compression loss and oil consumption. Requires specialized knowledge for diagnosis and repair.
Carburetor Tuning:
Carburetors can be finicky and require regular tuning to maintain smooth operation and fuel efficiency.
Electrical Corrosion:
Age-related issues with wiring insulation, connectors, and grounding points can lead to intermittent electrical problems.
Rust:
Common in vehicles of this age, particularly in areas prone to salt exposure. Floor pans, wheel wells, and rocker panels are susceptible.
