the choke unit itself should get warm within the few first minutes of running you will have to remoove the plastic cover it has so you just have the bare choke mech to be able to feel the heat from it.just so you know the carb does have a seperate choke jet which may be blocked if it seems to not be working.it should have a gurtner carb on it.
