cleaning my carburetet,it has the original shellac cover'd float,wondering what today's gas might do to it, I know it can wreck so rubber.
Ethanol in the gasoline may soften or dissolve shellac on an original float.
The cork float in my Dodge fuel gauge sank like a rock. I had to get a brass float.
I was afraid of that,darn LANG'S HERE I COME.thank's guy's
After the float has had plenty of time to dry out, seal it with "hot fuel proof model airplane dope".
Two cycle model airplanes engines run alcohol fuel with a significant fraction of nitromethane added.
Mark, is that stuff still available ? I used it over 50 years ago to seal carb floats. Should be ideal for the purpose !
I think so, although I've been away from the hobby for a long time.
You can also buy nitrophly from Restoration Supply and carve your own float page 20 https://www.restorationstuff.com/pdf/RestorationSupplyCompany.pdf
Kwik poly or paint it with seals all
But let it dry out first
Be careful how much you use. You don't want to make it too heavy.
Any hobby shop should sell fuel proof dope. I have used it for years, but recently I pulled the G off my 15, and the dope had sloughed off in pieces from the cork. Not sure what happened, but going back with new float.
