    Hi again everyone.
    I have just worked out why the Rotary is running like a hairy goat.
    The choke seems to be stuck in one position, basically half on.
    After removing the tank I can see that the plunger (?? brass pushrod thingy that is conected to the cable ) is stuck.
    Its difficult to diagnose as the Plenum chamber covers the view of the carbys.
    Has anyone ever had a seized or stuck choke system?
    I have manually pulled the choke cable and the lever mechanisms are jammed.
    Cheers Mark
