I need to understand the carb better for a variety of reasons, so I decided to pull it off and start from the top. I am rebuilding it using the GM shop manual and the instruction that come with rebuild kit. I am at the step where I need to remove the hinge pin for the float... I can't seem to get it to clear to pull the pin out and I'm not understanding what I need to do from the manual. What am I missing to make it happen? I don't want to force anything.

Also, what items should I absolutley replace while I have this thing this far apart? There is a lot of nasty stuff in this thing. Float? Needle? Choke thermostat?

If I have to replace the thermostat, what kind of rivets am I using?

 

The float pin should lift right out of the body with the float, and slide right out of the float itself.

You should replace everything that comes new in the kit (you will have some extra pieces, since the kit will cover more than one specific carb). The float itself is another wise part to replace that doesn't come in the kit.

Unless you have a known problem with the choke thermostat, you shouldn't need to replace it. The kit should show how to drill out the rivets, and have self-tapping screws to replace the rivets.

When I do this job, I lay out an old bath towel on the bench and start in the upper left corner laying out the pieces as I take them apart per the kit sequence. I can then see what comes new in the kit, and replace those parts (after soaking the metal parts in carb cleaner and blowing out all of the passages) as it goes back together.

 

Thanks for the info, it is helpful. I am running into a time crunch here because I am going to be out of town for 2 weeks, so this is going to have to sit for a bit unfortunatley. As I am taking it apart, I am trying to leave it in a logical sequence so its not so confusing going back together.

I am corious to take a second look at that float hinge pin. Clearly I'm missing something. It just doesn't seem to come up high enough to come out. When I lifted in the needle below it fell out of place.
