First: 787 Carb vs 800 RFI — What’s the Difference?

The 787 carb and 800 RFI engines are closely related but use different fuel systems. Identifying your engine correctly is critical before ordering parts.

Quick clue: Visible carburetors and no electronic fuel injection system.

800 RFI Engine

Fuel-injected version using Rotax RFI system. Found in later models labelled “RFI”.
