Apex Seals:
Wear and failure of apex seals is a common rotary engine issue; proper maintenance and break-in procedures are critical.
Carburetor Issues:
Tuning difficulties, diaphragm wear, clogging, especially with age.
Oil Consumption:
Rotary engines naturally consume a small amount of oil for lubrication, but excessive consumption can indicate seal wear.
Chassis Corrosion:
Common for vehicles of this age, especially in rust-prone climates.
Electrical Gremlins:
Aging wiring harnesses and components can lead to intermittent electrical faults.
