stiff gas pedal

here's a stupid little one that bugs me...............the gas pedal is stiffer than it should be,always has been sinced i owned it.so,i replaced the cable with a new one,routed with no kink,disassembled entire foot pedal setup ,firewall mount greased.got a new carb,not for that reason.and the damn thing still stiff,not bad after your going.must be in that pedal assembly somehow.i'm about ready to blow a 100 bucks on some aftermarket lokar hot rod pedal setup or something.

Re: stiff gas pedal

I am sure you already tried this but didn't mention it, but how about a lighter return spring on the carb?

Re: stiff gas pedal

I'm not sure what kind of brackets you're using for your cables near the carb, but with mine, the bracket can be turned side to side by loosening the nut that holds it down. If I turn it to the right, it loosens the cable, and to the left will tighten it and make it stiff. Sounds like you just need to adjust your cables...

Re: stiff gas pedal

If the cable is to low on the carb linkage it will be hard to push. See if you can move it up.

Re: stiff gas pedal

I have the same problem but it hasn't bugged me enough to hunt down the source. I guess I know what not to try now.

Unfortuneatly for me a lot of money too!?!

I was just thinking about an '85 K5 I used to own.
My sister was buying it from me - she had a situation so I more or less gave it to her and she was fixing things on it as she drove it.
The carb was having issues so her then boyfriend replaced it with an Edelbrock. This involved using a spacer under the carb.
The driveline broke and ended up cracking the case of the transfer case so she gave it back to me.
After getting it back on the road I noticed that when giving it gas it was real hard to a point then it got easy. This was real annoying especially since it was a manual tranny - you would end up flooring it when it got over the "hump".
The spacer was because of the EGR valve. I removed the EGR valve and was able to remove the spacer. The throtle was smooth as silk then.

Short story log, like was said before check the angle of the throtly cable. It made a huge difference on that K5.
