These otherwise simple things can become difficult when frustrated and looking again after some needed sleep will help jog your resembley memory. Looking at my Clymer manual which has excellent illustrations on throttle cables installation/ removal it all becomes clear again to me. Basically if you know and understand which cable is the pull and push, their loosening lock nut adjuster locations near the throttle and and carburetor mounting bracket, loosening these adjusters and disengaging the cables from the throttle, will give you the slack too work with the cables, provided you have not completely installed the carburetors which need to be loose to get the cables back into the throttle wheel and mounting bracket correctly. If you cant remember this by hart from disassembly, you need a good manual with illustrations to get it back together.
