I left about a half gallon of gas on the ground at my last motorcycle club meeting. A little embarrassing to say the least. Glad no one was smoking or a whole line of vintage bikes would have gone up in a fireball. Turns out one of my floats filled up with gas and doesn't float anymore. I know, I should have closed the petcocks, I almost always do. What is especially vexing is that this particular float was only 1 year old and not exactly cheap. Luckily I had saved one of the old floats and was able to reinstall it. The only reason I had replaced it in the first place was that it was a little heavier than spec. The question is, are new floats for PHM's as good as the old ones? Is there something in fuel these days that is dissolving them more rapidly? Anyone else suffering from flooding floats? The interesting thing is that there is no apparent hole in the float. It's just completely full of gas in one of the chambers. The new floats are a translucent white in color, even after one year. The old float, which I'm using now, is a solid yellowish color. I'm worried about the other carb, it's also got the newer float.
