After about 125 hours on my RV-12, I was beginning to think I would be one of the lucky few without carb float problems....I was wrong! Doing my night currency last week, I noticed the smell of fuel in my cabin for the first time. Also, my idle had been gradually getting rougher. After shutting down for the night, I opened the oil tank door on the top cowl and the fuel smell was very strong. With a flashlight, I could see standing fuel in the drip tray! I removed the top cowl and dropped the float bowl.....sure enough, the floats were mostly submerged. After letting them dry, I weighed the pair and they were 11.4 grams. I then checked the left carb floats, they were not as bad yet, but still over weight at 9.5 grams. I just ordered 2 pair of the latest PN, 861188. Wow, $300!! I guess I have a new and expensive 'consumable', this engine is 1.5 years old with 125 hours. Based on everything I have read, I am not confident that the new floats will last any longer. Maybe it's the ethanol in this California fuel. I just wanted to add my experience as a data point.
