My 214 runs decent and all, but I've noticed when i pull the variator lever back to slow tractor down, it makes a slapping or knocking noise under frame? Other than that, when I move lever forward to go faster, it seems to be working fine.

I didn't work on the variator on my dads 214 but from what I understand it is a lever that moves a pulley to adjust the speed. something might be loose so it jumps and makes a knocking sound. Im not an expert on these (yet :D ) but that would be my guess.

I would guess the middle pulley in the variator is binding on the center shaft of the assembly or the tensioner spring is out of adjustment/needs replaced.

have you put graphic powder on the variator, so the the center can slide back and forth?

have you checked the secondary belt idler and spring?

also check the secondary belt idler pivot bolt, sometimes the brushing gets worn and causes some problems.

Hollowed out bore on that bolt is my guess, also.

Got a schematic by chance so I can see what part you are referring to?
Thanks
