I found one (and bought the last one) through Rock Auto, but they're discontinued. My local O'Reilley can't get another one. Napa doesn't stock them.

 

Only way I know of is to buy a core carb.

 

Someone on the forum has a bunch. Note I said ON the forum. Don't bother trying to track down Sterling as he hasn't been on the forum in like forever. In other words, start a want to buy thread or something. Heck I'd offer you some of mine but I haven't looked at Nikkis in a while. I'm sure someone else will have a couple though.

 

Remember to test used floats by letting them float in a (sealed, outdoors) container of gasoline for a couple days... to make sure they don't sink.

 

I'll put up pics of my NEW float that I ordered this weekend if/when it arrives.
