I have a 92 f2 with a 95 f3 swap (or so I was told) I can get this thing to run for about 10min, when it gets to norm. temp. it seems to choke out and will not restart until it cools. I've noticed, at the back of the carbs, two open tubes(one on each side of the fuel line) dripping fuel. I'm not sure where these lines go to. If I blow into them, fuel shoots from the small ports out side the "carb trumpets" Please help?

I believe the two open tubes are overflow tubes for the carbs. If fuel is leaking out it could mean you have stuck needles or bad floats. As for the bike only running for ten minutes, are you sure the choke isnt stuck?

Sticking needles was something I overlooked. I'll have a look at the choke while I'm digging around in this thing. Thankx alot.

Stuck floats will send fuel out of those tubes. Try tapping the side of the float bowls with something that won't damage them (e.g. broom handle, screwdriver handle, etc...) to try to free them up. You can tap with some authority....just not too much.
