Stumble with rebuilt Thermoquad /340

^^^ this as said above....it this is not Ok....... try adjusting to the next hole on the pump arm....also, another possible problem is to check with engine idling tap on the secondary plate and it should rock about 1/8 inch or so back and forth....If there is no play in it, that is your problem....need to bend the linkage to create a little slack in the secondary plate....also if plugs are lean need to fatten it up by adjusting screws outward 1/2 turn at a time
