I kinda thought the linkage was not the answer. I have the shop manuals on this engine so I'll do some homework and see if I can locate the throttle body and the large brass screw you described but since I'm really not familiar with this engine at all I'll probably go the safe route and take it to a shop that does knows the 110 engine. If anyone can recommend a shop in Tucson Az that is experienced with the 110 I'd appreciate their name Thanks very much....Desert
