Thx. I won't be running it that way because my whole carburetor broke off (see h t time machine thread) but I ran it 2 days that way. I fixed the float with a solder iron. It held up fine. The leak was 1.5mm wide * 3.5mm long. It was located inside the inner ring wall. Since the ring hole is only .9cm across I used an extra compression spring, barely larger than the solder iron tip, slid over the tip, and half a sewing needle (the whole needle would not transfer enough heat to melt) wedged between the 2. Took awhile but it worked. I'd recommend the needle on exterior plastic repair too. A regular tip has too much surface area and/or heat (depending on tip- size; shape; wattage) to allow a quick fix without a really steady hand. Also think it wastes more plastic than necessary.
