Rotary Engine Wear:

Apex seal wear and carbon buildup are common, leading to compression loss and rough running if not properly maintained.

Oil Consumption:

Rotary engines naturally consume some oil as part of their lubrication system; excessive consumption can indicate seal wear.

Carburetor Issues:

Carburetors from this era can be prone to clogging and require regular cleaning and adjustment.

Cooling System Maintenance:

Proper cooling system maintenance is critical to prevent overheating, which can be detrimental to rotary engines.
