One thing I have not seen mentioned on this thread...
Perhaps it is no longer an issue, it's been 20 years since I learned this the hard way. The older rebuild kits had a brass float that looked like a tiny gas tank. The newer kits have a foam float that looks like a chunk of plastic. The foam is covered by some sealant material. If you adjust the float by pushing on the float itself to bend the arm you will crack the coating where the float is bonded to the arm. The gas (especially gasahol) can attack the foam, and in a few weeks, when it is dumping raw gas down the venturis you will disassemble it and see that your float has shriveled into something resembling a large raisin.
I learned the hard way to always make any necessary bends in the float arm using two pairs of needlenose pliers on the arm, and do not touch the float.
I do not recall the model of the carb I did this on, but it was on my '67 Jeep with a 225 V6. I also rebuilt the Carter AFB on my '69 Javelin about that time.
It's been probably ten years since I have had to rebuild a carb, but I am planning on doing the Qjet on my panel this winter.
Experts, is there still an issue with gas attacking the float if you damage the coating of the float?
