I'm diddling around putting new throttle and choke cables in my old garden
tractor.

My new throttle and choke cables are about 2' too long.

any reason I can't cut those down?

They're both armor sheath with stiff wire cable inside the sheath.

I assume I'd just pull the cable back to where it clears when I cut the
sheath, then put the cable back in place and cut it to length.

Advice appreciated.
