Alright so I have an 82 PU, it has a 3" body lift and 7" springs.

I changed from a Webber 32/36 to a 38. Now and then, my gas petal will feel like it's got something stuck behind it (ie. you can't depress the petal).

Anyone else had this issue? Any ideas?

 

you might need a stronger return spring, I had to add one with my 32/36 setup on my 87.

oh wait you said hard to press the pedal, this leads me to maybe the carb is exactly on the base plate straight and the butterflies might be catching a little on the base plate. Had something similar happen the first time I rebuilt my aisin.

 

Thought of that, but it binds both ways. Like if I have the throttle on when it does it it won't let off, if I'm idling it won't let me give it any.

 

read my edit above as well, but have you tried eliminating a bad throttle cable by trying the linkage without the cable hooked up? there is a possibility the wire in the cable is frayed as well.

 

yes i have had this problem before on 2 seperate occasions, both different fixes.

1st time - the cable was loose and it kept getting stuck in the little grooves on the rotating part of the carb. A quick pump of the throttle would lossen it up sometimes and other times i had to pop the hood and over rev it to get it loose until i fixed it.

2nd time - the adjusting nuts attached to the support on the cylinder cover, directly on top and back on the cylinder cover. The throttle cable adjusting nuts came loose and would get stuck on one side of the support. Causing no movement in the pedal. Had to hand tighten it in place until i could get to a wrench.

O \ O this is what it should look like, the \ being the suport and the O's being the adj nuts. the nuts adjust the idle speed, so put it where it idles best and tighten the crap out of them. also, make sure your support isnt bent like mine was.

 

haha I have that problem too with mine as well. still have yet to figure out a real fix for it. for now I just let it idle at 1000 RPM that way.

 

HA! Classic! Well, i just remembered that the first problem i had was caused from the second problem i had. I had a loose adj nuts and because of that there was too much slack in the cable which caused it to catch the teeth on the rotating part of the carb. Might help.. obviously there is too much slack. have someone jump in and pump the throttle a couple times and you look at the cable and see what it does. Might help i think. good luck.

 

I'll have to look into it, I always thought it was because the throttle cable was too tight, but hasn't really bothered me too much.

 

nah if it was too tight, then the idle would be too high. when you push in the clutch* pedal it pulls the throttle cable with is attached to your rotator on the clutch* and it rotates, allowing more fuel and air through.

**EDIT : I meant the GAS! pedal, not clutch... my bad

 

I might be missing something but the clutch is somehow connected to the throttle cable? other than the pedal bracket, I don't see how it's attached.

 

I'll look at those things tomorrow.

I'm noticing that when it does it, I'm usually on some sort of incline, or flexing a bit.
