You need to do some careful looking before you pull hard on anything in that linkage, insydney.


In that picture you see on the left, a GXV120 carburetor and on the right, a GXV140 one. Note that the one on the left has a fuel tap, the one on the right does not. Otherwise they are much the same.



In this picture on the top left you see the throttle link connection (the black plastic bell crank sticking upward from the top of the carburetor). In this side view, you can see that the connecting link passes through the upper part of the crank, and pushes downward. The link cannot normally move upwards out of position accidentally, because of the projections on that upper part of the bellcrank.



In this picture you can see that there is a slot between the projections at the top of that black plastic bellcrank so that there is only one rotational position in which the connecting link can move upward, and escape from the bellcrank. If you try to move the link upward in any other position, and apply force, you'll just break the plastic bellcrank, which is irreplaceable. One new carburetor required.

The choke bellcrank does not need this tricky rotational position complexity. The wire link is bent 90 degrees after it passes through the bellcrank so it can't come out while the carburetor is installed. However with some ingenious manoeuvering you can slide the carburetor outward on the studs and wriggle it around to unhook the choke link. Many people with less dexterity bend the link a bit to remove and reinstall it, then straighten the link afterward if they have bent it.
