Fit and compatibility notes for the carburettor body

This replacement carburettor body is an RC-scale accessory intended for maintenance and tuning of OS glow engines. The item matches the product identification 61B 91HZ and serves as the core housing that locates the needle valves, throttle linkage, and mounting points on compatible carburettors.

The description focuses on fitment and function rather than claiming universal compatibility; check physical match and mounting points before installation. This body is intended for hobby use on model engines and must be paired with the original carburettor components when reassembling.

Which OS models are likely to use this body?

This listing is identified as OS29085100 and 61B 91HZ; cross-reference those codes with your engine's parts list to determine if this body is specified for your carburettor model.

How precise must the mounting match be?

Very precise. The mounting faces, hole spacing and throttle shaft alignment must match the original part to avoid misalignment that can affect throttle action and sealing.

Can I mix parts from different carburettor versions?

Mixing components from different carburettor variants risks mismatched geometry. Only combine parts if their dimensions and mounting interfaces are confirmed to be compatible with the 61B 91HZ body.

What should I check before ordering this spare?

Confirm part codes on the original carburettor, measure the mounting points and compare throttle linkage orientation to ensure the OS29085100 body will fit without modification.

Is professional installation recommended for compatibility issues?

If you are unsure about part matching or need precise alignment for performance builds, seek help from an experienced hobby technician to avoid damaging the carburettor or engine.
