The Stovebolt Site Forums The Shop Area Engine Shop How do ya loosen up a new choke cable?

This goes for the throttle cable also. Its like I have two feet on the dash trying to push and pull the choke cable., without knowing if its closed or what. I would think there are 'smoother' cables for the Rochesher 1b .

Did it work easily before you hooked it up?, maybe too sharp on the bends?

Hello. zip-a-dee-doo-dah

Take off/out the cables from the housings - remove each cable from its housing.
Clean each cable and sand-until-shiney.
Lubricate each cable (light oil or very light/white grease).

I have found that many cables/housing have been "kinked" (in the old days) - because return springs too-easily pulled the throttle/choke cables "inwards".

You must do what Tim says or you will break off the knobs and then you will throw the whole thing away and struggle to find original ones again. When they are installed, there will be friction from the bends in the cable and there will be resistance from whatever they operate. So they must be able to work with no effort at all on the bench.

Yup!

all the original ones i pulled apart and cleaned had three distinct shallow waves in the wire near the knob to induce friction to give them a bit of holding resistance against the carburetor springs, these waves are a couple inches spaced and extend a half foot or so down the wire from the knob.

when you are cleaning the wire and removing the bad kinks consider that if you make it perfectly straight and smooth you will end up with the opposite problem.

when i'm driving through the field or on rough roads, the cables always vibrate back in because the return springs are so strong, i would need that "two feet on the dash" tension to keep them from moving back in
i figure these knobs are only for stationary application like keeping the engine running on a cold start,
the throttle knob probably could never have been used as a cruise control, it would have worked it's way towards the dash with vibration even when new,

there are after market cables from the 50s to replace the OEM ones that would slide in on their own. they have a locking lever device so they stay put, and you can make fine adjustment by screwing the knob in or out, or you can override the holding clamp at any position and force it over the spring loaded detents
one of my 2 Ton's has this kind of knob in it, much better than the original, something to look for at the wrecking yard next time your there.

My 1971 Blazer had a factory screw throttle as I remember.

I had a similar problem after changing carbs. I tightened the screw holding the cable to the carb too tight. Loosened it and all was well. Perhaps your problem too?

Thanks, disassemble, inspect, clean, lube, reassemble.

So I did most of the work. What does work on this one is to twist the knob slightly clockwise and it becomes looser and then it slides out and in fine. It even worked this morning. Hoorah.
