good morning Jerry my name is John. Is this machine one that you use often and this just all of a sudden happened?

Customer: replied 3 months ago.
Expert:  John Oliver replied 3 months ago.

remove your air cleaner and verify that the butterfly "flaps" in the carb are free. there should be other linkages that are solid besides the cable. those linkages are attached to the engine govenour and control the actual movement of the carbs butterfly. make sure there isnt debris stuck behind the carb causing them to bind

Customer: replied 3 months ago.
the flaps are free and clean with nothing in the way
Expert:  John Oliver replied 3 months ago.

when you look inside are both flaps closed? the first one you see is the choke and the second is for throttle

Customer: replied 3 months ago.
no the first 1 is open and is free when unhooked from linkage but when hooked up its open 3/4
Customer: replied 3 months ago.
the first 1 is throttle and the second is choke
Expert:  John Oliver replied 3 months ago.

ok perfect. what is keeping that 3/4 open? is the linkage stiff? is it bent? when you run the engine can you manually shift that linkage to idle?

Customer: replied 3 months ago.
cant see anything holding it open its can be manually idled down and dont see any bends in the linkage
Expert:  John Oliver replied 3 months ago.

i suspect that maybe you are missing a spring on that linkage. what is the machine make and model and maybe i can find a parts break down to verify

this is the best pic i can find of the parts break down. im afraid that you may need to ask the service department where you plan on ordering parts from if they can print you a location of where these springs belong

i will attempt to find a better pic in the mean time
