evening guys, i'm refering to my lx565 but it's probably a general fix my Aux handle (the right side handle) won't stay locked because the small "L" shaft is loose and keeps falling down , allowing the handle to pivot. i've been to Messick's .com for a parts breakdown but it's not clear to me how the pin is able to stay in the up position. the "L" shaft does have small detent in it ..can someone explain? TIA, steve
