Hey guys, first day on the forum. I came here because, well, I'm stuck.
I pulled the carburetor, had it rebuilt, I'm putting it back on, but...
I have... this spring...



I have no idea where it goes...
I have the manual, but it's completely useless. I've tried to find pictures of a carb connected inside the motor, but I've found nothing. The rebuild kit I bought makes no mention of this, because I think it has something to do with the linkage. That's just a guess though.

Here's a couple pictures of what I'm working with...







Thanks for whatever help you're able to provide. There's not supposed to be parts left over...

 

Man that looks like a spring that goes in the rear drum brakes

 

It's really not.
I have not opened up the brakes on this thing ever. I've only owned it for a few months.

113,000 original miles, can you believe that? My neighbor bought it new.

 

I know you like pictures

 

Nice lookin rig man good gas mileage to

 

I wish I could help with the spring but all I run is webers if it was a weber I could help you out

 

Yeah, it's definitely the Aisan carb

 

Rebuild kit didn't come with any springs? I know they usually don't, but just checking...

It looks like the throttle connection spring (not sure of the real name). Kind of looks like the spring that...how to explain this...

When you pull the carb, the only linkage to the truck other than the four bolts on the base and the vacuum and coolant lines is the metal piece that attaches to the throttle cable. A metal bar goes into kind of a slot in the back of the carb. A spring attaches in there...

Can't tell from your photos if you have that attached or not. Maybe I'll take a photo of mine. There aren't many spring there.

 

Oh man, that would be awesome. I went to the junk yard to try and find another truck with a carb like mine, just so I could look at it. They didn't have any

 

Is this it? The back of the carb, where the coolant lines attach, is in the bottom of the photo. Looking down from the top.

 

The 20R 2WD carb setups are a stupid design. The fact that the throttle linkage bolts to the firewall can cause inconsistent throttle response since the actual motor torques while the body stays still.

So that spring actually hooks on to a friggin hose clamp?!?!1 I did that earlier and I thought "no way, they couldn't possibly have designed it like that" Thanks so much for the picture man, you're the best

 

After taking another look at this mechanism... I don't get it. Honestly, it doesn't make any sense. What is it... supposed to... do??? The other spring that's mounted to the firewall does exactly what this looks like it's supposed to be doing, except better.

 

Can you take a closer photo?

It doesn't attach to the hose clamp. It attaches to a little metal "hook" right next to where the hose goes into the intake, and over the throttle on the other side. I think the point of it is to help return the throttle when you let off the gas.
