never crossed my mind at the time i shall replace them and see what happens

Jeff, just to answer your original question. Yes those floats sometimes can get soaked with fuel. Take them out when they have been sitting in a full fuel bowl and weigh them comparing to the weight of a new one to see if they have gone bad. Unfortunately you have to buy a new one to get the weight in the first place unless you can borrow a new one.

Make sure you buy quality floats when using nitrophyl, there are some cheap ones out there that don't last. BLP is a great source for quality Holley parts.
