Topic: Help routing throttle push/pull cables - cb750 k7 (1977), throttle shaft stuck?

[tommm]

I'm reassembling my cb750 after removing the engine and am running into a little trouble when routing the new throttle cables.

The slack of each cable would indicate that the Pull Cable is routed through the bottom of the throttle mechanism, and the Push cable would go over the top.

When I route them that way, I'm unable to pull the throttle at all.  Could it be possible that my throttle shaft is stuck?  Or do I have the cables backwards?

Correct...Pull cable goes under the bell, push cable on top.
are your carb slides stuck?

I'm guessing the slides must be stuck.  I removed carbs and cleaned the bowls last year, but they've been sitting since.  Any tried and true way to unstick them?

Take them out and clean them    ..but before you do that, just try to actuate the throttle bell.
If they are truly stuck, a blast from a heat gun down the coffin top might loosen up the varnish

Heat gun on the carb bodies where the slides sit.  Heat the carb bodies. 
With the tops off you can see a bit of motion from throttle wiggle on the moveable slides and none from the stuck ones.

Do not use excessive force to make them budge, or you will need another carb sync, at least, or bent parts.

Do not lever the slide bottoms for freedom as they are soft and you'll have a nick in the metal.

A solvent in the slide bores also helps.

Cheers,

Thanks guys, a little heat and a shot of carb cleaner did the trick!
