Castair TCSP-H-0813-B — Airline Throttle Control for Honda Gas Engines, 8–13 HP
The Castair TCSP-H-0813-B is an airline-type throttle control designed for Honda gas engines in the 8 to 13 HP range. Unlike the cable-type TCLI and TCLP throttle controls, this unit uses compressed air pressure to actuate the engine throttle — the compressor''s own air pressure signal drives the throttle actuator when the pressure switch triggers. Airline-type controls are common on portable compressors where routing a Bowden cable from the pressure switch to the engine throttle is impractical or where the engine is mounted in a location that makes cable control difficult.
The SP in TCSP designates the airline (pneumatic) type, H indicates Honda fitment, and the 0813 covers the 8-to-13 HP engine range. The -B suffix distinguishes this variant from similar controls. This is the part that goes on the engine throttle lever and connects to the airline from the pressure switch — if the diaphragm or actuator in the original has failed, or if the airline fitting is cracked, this is the direct replacement.
Key Features
- Airline (Pneumatic) Actuation: Uses compressed air signal from the pressure switch to move the engine throttle — no cable routing required
- Honda Engine Fitment: Matched to Honda GX-series engines in the 8–13 HP range
- HP Range: 8 to 13 HP — covers mid-range portable gas-engine compressors
- Pressure-Switch Integration: Receives pneumatic signal from the compressor''s pressure switch to throttle engine up or down as demand changes
- Cast Air OEM Specification: Correct replacement for Castair gas-engine compressor configurations using airline throttle control
Technical Specifications

Note: For larger Honda engines (8–20 HP) requiring cable-type throttle control, see TCLI-48 or TCLP-48. For smaller Honda engines (5–6.5 HP), see TCSP-H-5565-B.
When You Need This
- The airline throttle actuator on a Honda-powered Cast Air compressor is not responding — diaphragm failure or cracked housing
- Engine runs at full throttle even when the tank is full — throttle actuator is not receiving or responding to the pressure signal
- Rebuilding a pneumatically-controlled Honda gas engine compressor
- The airline fitting on the existing throttle control is cracked and leaking air
