throttle cable

Is there a trick to getting a throttle cable easy to push. This is on a 55 chevy and its one of those mr. gasket cable but I have had lokars and its always the same hard to push ....thanks Jason

 

theres your problem. traditional hotrods use rods, not cables

cables are designed to *pull* not push. If you want it to push, you have to have a spring pulling from the other end

Is it BO zure or boss i er?

 

push a cable? usually throttle cables are pull

what kind of setup do you have? pictures?

 

bo zure....lol, it is a pull type, what I mean is the throttle pedal is hard to push....I cant see that the cable is in any tight binds or anything

 

Take the spring off(not running) and see if it's still hard to push

 

Oilman, are you old?

 

Oilman, oil your cable...

 

44 are you old?

 

yep

 

We've always used Lokar cables and some of them have had to be bent on severe angles to clear the engine, and none have been hard to operate. Either you have some bind in the pedal, too much spring tension, or your carb is hanging up. Maybe you have a bad angle of pull too.

Start disconnecting things and see where the binding is occurring. You have something going on that is not caused by the cable itself.

Look at the angle this one on my Son's Olds is running at, and it is opening two fours with 3 stiff springs on it, and it still is very smooth and easy to push.

 

thanks Don's, mine is not at all that much of an angle so I will start disconnecting stuff and check, thanks for the help

 

oilman, you got a PM
I might be able to help you

 

With 2 carbs you can hook the cable to the front carb . This will make more room for the cable. The large hole on the carb linkage is for the cable point.
Don , does these carbs both open fully ? I see that the linkage between the two carbs are not in the same pivot holes. Just asking.

Who said it had two carbs ? Oilman what kind of pedal are you using ?

 

you've done it now, oilman. This thread may go for weeks

 

lol...I got it manyoldcars...I will call you tomorrow, it only has one carb. on it and has the stock pedal with a piece welded to the stock bell crank that connects the cable

 

My post was to Don's picture. sorry

 

How long an extra piece? Maybe that throws the leverage ratio off a little and creates more effort

 

it might be too long....or have the ratio off, Im still going to start taking stuff off and checking

 

i have nothing to add , just want to keep this thread going

 

when I get it figured out I'll let yall know what I did

 

There are cables designed for pushing. I have never seen one used as a throttle cable, and I don't think it's a good option for that.

 

calm down and think of England.
He promised that he will tell us

 

My post was nothing more than additional info. Why would you think that was inappropriate, unnecessary, or getting exited?

 

James, when you use the linkage as progressive you have to mount them with one in the higher hole and on in a lower hole, otherwise the second carb will not be pulled all the way open. We played with the progressiveness of his carbs to dial it in and we found his motor needed as much carburation off the line as possible, so we adjusted it so the second carb is coming in at about 1500 rpms. It really woke it up and the engine seems to like all those cfms.

I ran the two four setup on my 27 with straight linkage for years and only recently went to progressive, but I really didn't notice any significant difference either way.

Hi Don
That makes sense . I run straight up linkage . I needed all the cfms I had. Does that progressive linkage not starve the front cylinders at low end rpms ?

James

 

I guess oilman is working in the garage. He promised!

 

Supposedly not. The intake is an OFFY 360 degree, which is designed to evenly feed all the cylinders............at least according to Mondello, who we bought it from. We've been taking plug readings a lot since installing it and all the plugs are burning the same.

Don

 

I really really believed that oilman would keep his promise (sigh)
