Re: /2 type 120 carb difficulties
I am trying to go through the tune-up procedure and I am to the throttle / cables / carb interface.
I cleaned, lubed and set the throttle tube/gear and routed the cables for the least bends. I screwed the cable adjusters at the slide tops down as low as they would go. When I put the slides in and screw the tops down, one carb has a nice bit of cable slack, but the other side has no slack and pulls on the slide right away.
I think I want to get a new set of cables. Here is where my issue is.... the end of the cable won't pull out through the top of the slider top.... see the pictures. I can cut the end of the cable off (??!!) but I am afraid any new cable I buy will have the same sort of end and I won't be able to get the cable INTO the top....?
Am I missing something? My bike has euro-low bars, I believe. Thanks in advance!!

Re: /2 type 120 carb difficulties
I tried to get it out....but I will try again. I was thinking maybe they pinched the end on after sliding the bare cable thru.
I know about the little missing piece--- probably one of the other previous owners (over the last 56 years lol) lost it. Trolling around parts sources, I don't see those locking bits for sale...? The top seems to be pretty snug from rotating when it is screwed down.
The bike is an old gal, she will never be a show bike, but I have wanted one for at least 30 years and feel lucky to have one at all give how prices have gone bonkers

You don't need the tab if you realize it's just to index the cover to the correct place on the carb: you can see where the tab broke off, and the slot in the carb where it should fit...

Re: /2 type 120 carb difficulties
sorry for the stupid question at this point: why it is no mentioned also to check the spark plugs after tuning the carburettors? if the spark plugs appearance suggest a non optimal mixture, adjustment of air screw should be done accordingly i assume. Am I wrong?
