Hot Air Choke

Warm engine to normal operating temperature. Check choke valve. Choke valve should be fully open. If choke is not fully opened, touch choke housing and hot air inlet pipe or hose to determine if sufficient heat is reaching choke thermostatic spring.
If choke housing or hot air inlet pipe is not getting hot, check choke housing, choke heat pipe or manifold choke heat stove for restricted passages. Repair or replace components.
