Weber float; brass? neoprene?

[l75eya]

Has anybody had issues with the floats in their DGVs cracking? The neoprene ones?

I'm in the midst of rebuilding and cleaning all the crud and crap that got in to my less than 1 year old brand new carburetor, and discovered the neoprene float cracked. Both sides.

I can find replacement floats in the neoprene and brass. The brass float is twice as expensive as the neoprene one.

 

I'm thinking of just getting another neoprene replacement and checking on it periodically. I can't imagine what could have caused my float to crack, though I have sent a few things down the throat of that carburetor.

I always run 93 octane but it has seen an entire can of carburetor cleaner and some wd-40 as well at one point as an emergency starting fluid.

 

In addition to those things, all the calcium deposits and rock salt and dirt and grit from the contaminated fuel it had been getting.
