Flat top SU float pin removal

[g9m3c]

I'm in the middle of rebuilding my carbs, and I can't figure out how to get the float pivot pin out to remove the float. There is a screw in plug on the side of the carb, and the end of the pin is under that. However, there's no way to push the pin out from the other side.

Anyone? I still haven't figured this out.

Not too many people here that have much flat-top experience. More often they just replace them. Maybe sblake01 will see this, I recall he has some experience with these.

This is looking down through where the plug screwed out.

The other end of the pin is under the body of the carb here. There's no way to push it out the other side. :mad:

Any ideas to get this thing out?

Try holding it with the pin in a vertical position over top of a bucket to catch it and repeatedly tap it sharply with the hard plastic end of a screw driver handle or something similar from the other side. It will only be the slight wear grooves on the pin holding it in place on the float arm. While doing this try taking the weight of the float off the pin by holding it up with one finger.

You'll probably have to use a pair of small precision pliers or jeweler's pliers to get it out. Be careful not to bend the float stopper.

I've tried that, and just can't seem to get a good grip on it. I think it must be a little bit stuck. I may drill a small hole on the other side of the body where I can stick something in there to push it out. I assume I could use a little jb weld to stop the hole up and I'll be good to go.

Have these carbs been sitting up out of use for a period of time. If that's the case, they might just be gummed up and a little carb cleaner/solvent around the pin might be the answer you're looking for.

They've been sitting for 3 years.......going to spray some carb cleaner now.

Hmmm.... I can't tell from looking at an online photo of the float, or from your pictures exactly how the float sits on the pin. There is a small note on the bottom of the page EF-28 in the 1974 FSM that says "Note: The float and needle valve parts cannot be removed."

Since replacement floats are available, there must be some way of replacing them. I'm wondering if there is a possibility that the pin stays in place and the float comes off some other way, but by the look of the photos that would seem impossible without mangling the float beyond recognition. Otherwise I'd agree with geezer that it's got some wear groove, or it's slightly bent somewhere along its length. Does the pin wiggle back and forth at all?

I'm afraid I can't be of much more help beyond that, and these carbs aren't frequently dealt with.

[geezer]

The wear groove will not be in the pin itself but in the layer of crude that is coating it. Find a piece of plastic tubing that will fit over the end of the pin with a tight interference fit and then slowly twist & turn it out. Or use a spring steel pin that will push on and grab a hold of it. It seems like a simple task to me and makes me think you are never going to get these carbs running satifactory. I think your best bet is a round top swap.

Ahaha, thanks anyways. You're only the 8th or 9th person that has told me to swap to round tops. Like I told another guy, the car has 62,000 miles on it with flat tops, so.............

As far as you saying "it seems like a simple task," well, have you ever done it? If so, please fill me in on the simplicity.
