Yes sir, using those plugs and gap.
I found an old set of floats in my hangar and weighed them. All 4 were about 3.2 grams. I can't remember if I replaced them when I rebuilt the carbs due to being heavy or just did it because I had new ones in the rebuild kit. They may have been heavy and have dried out after sitting on the shelf. I'll let them soak in some fuel for a few ys and see if they gain weight.
Probably just smarter to order new ones from MS. I did call them today and as has been mentioned, they have them available again.
