Manual Choke Operation:
- For cold starts, pull the manual choke knob fully out to enrich the fuel mixture.
- Once the engine starts and warms up slightly, gradually push the choke knob in to lean the mixture.
- Fully push in the choke knob once the engine reaches operating temperature and idles smoothly without it.
Fuel Delivery:
- The carburetor features a single feed fuel inlet. Ensure your fuel system provides clean, consistent fuel pressure.
- The air valve secondary design allows for smooth transition to higher RPMs by progressively opening the secondary throttle plates based on engine vacuum.
