2 Stroke Considerations:
Requires proper oil mixture/injection for engine longevity; carbon buildup in exhaust and combustion chamber over time.
Carburetor Issues:
Can be prone to clogging if fuel is left standing for long periods or if poor quality fuel is used; requires periodic cleaning and adjustment.
