You're basically stuck with the return spring at the pedal, and the accelerator linkage idle return spring at the carb linkage. The springs are not necessarily designed to be stiff like American car pedals. You can put in stiffer springs, but the design of the pedal box and linkage is best with the standard spring design.
I actually prefer the lighter feel, because it makes it easier to hit a specific point in the pedal travel.

Does anybody know of a way to stiffen the pedal feel on the accelerator? Mine is like mush. I have already replaced the return spring, but it really doesn't help. Any ideas? Thanks.<hr></blockquote>
