Replacement carburettor body for O.S. Engine models

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.

Specifications

  • Item: Carburettor body 61B 91HZ
  • Material: Manufacturer unspecified
  • Model Number: OS29085100
  • Compatibility: OS engine carburettors, confirm model fitment prior to use

Use this carburettor body when restoring or servicing compatible OS carburettors, taking care to verify alignment of throttle and needle assembly during reassembly to maintain predictable engine response.

How can I confirm this is the correct replacement for my carburettor?

Compare the stamped or printed part code on your original carburettor to 61B 91HZ and verify the mounting hole pattern; matching those details ensures this OS29085100 body is the proper swap.

Will I need to alter the body to fit my engine?

No alterations should be required if the part number and mounting layout match. If there is any doubt, measure the mounting points and throttle linkage alignment before attempting installation.

Can I transfer my existing needles and throttle arm?

Yes. Reuse the original needle valves, throttle arm, and gaskets where they are in good condition, taking care to preserve seal surfaces and linkage geometry during reassembly.

Might replacing the body change engine adjustments?

Possibly. Wear or slight dimensional differences in the new body can alter needle seating and throttle feel, so recheck idle and high-speed needle settings after fitting the OS29085100 housing.

What tools should I have on hand for the swap?

Basic small-model hand tools are sufficient: small hex drivers, precision screwdrivers and a clean, lint-free workspace to avoid contaminating the carburettor internals during assembly.
