Gentlemen, thank you so much for this information. I'm going to find it useful. My 78 has been sitting for about a year with, now, really bad gas. I figured, what the hell, I'd just siphon off the crap in the tank with a hose before starting, so as not to get too much varnish in the system. Imagine my surprise, after sliding a length of hose into the tank, plugging with finger, and then pulling back to start siphon....to find that the hose had looped around the float internally, and my pulling back has served to simply tighten the knot. I'll be dropping the tank. Probably next week, as right now I'm laughing so hard I fear I just might drop a freaking wrench on my toe! Of all the dorky things to have happen ......
