Is there a brass float made by an other brand or someone which will work in a Holley G without major alterations?
I got a new float from Lang's made from modern material but haven't seen any brass floats from vendors. Seems like I read somewhere that back in the day they used brass floats from old Briggs and Stratton carburetors with some slight alterations. Don't know how true that is as I'm still new to this model t stuff.
There is one, I know because I have one. What application it came on originally is a mystery, and I doubt there is one you can order online. But you should be able to find one at Chickasha, Long Beach, Hershey, or one of the other large swap meets that have parts for old cars.
Mr Brown in OK made brass floats for all the early carbs.
There is a John Deere float that will work. I think they are hard to get now. I may still have one or two. PM me and I will look. Dan
A few years back, I chased down the B&S parts numbers listed in the MTFCA Carb book. They were all discontinued. The "composite" ones the vendors sell work fine. You'll need a hinge and the screws for it from a cork float.
The new G float kit from vendors is the answer to the old cork float replacement. I just transferred the old brass hinge to the new ring in one of the three Holley G carbs that had troubles leaking. The kit included brass bolts. Don't try to save the old cork, drill out the old rivets and mount in the exactly placed holes in the new ring. Twenty minutes and done!
Take a look at a Briggs & Stratton carb float for 16-18 HP engine.
I used one for a Kingston carb that the Lauson Lawton engine company used on their last series of engines like that >>> http://www.badgersteamandgas.com/photos/02c12.jpg
