Gas Spraying Carb Tee-Fitting.

Dude........ Read Toecutters Carb page. http://vfrworld.com/forums/mechanics-garage/22449-cleaning-carbs.html It'll stop the insanity.

 

Keys to easier carb installation are new boots well-lubed (i use brake fluid) on both intake and carb sides and angled to best advantage while half-on/ half-off the intake tracts with a gap where illustrated by the pointer.

You need to be constantly looking front and back, left and right to be sure things are lining up OK as you proceed. I usually begin by getting the rears PART WAY started, then move to fronts. Everything needs to partially aligned b4 anything is fully seated.

First time i r&r'd VFR carbs back in 1991 i stood on the assembly (like NC) for the final push, but now have some other techniques, which i do recommend but only with the greatest possible caution and ONLY for the final 1/4" of travel, the board (to spread the load) and rubber mallet technique, no disasters yet ! A few light impact blows seem to settle the carbs into place better than a constant pressure, but use utmost discretion. I've been blasted b4, and i'll get blasted again for this method, but WTF?; it works for me !

Final mate-up slides carbs into boots and boots onto intake tracts.

 

Yeah, be sure you have the upper collector connected to the carbs when you attempt to mount them to the engine.
Sounds like you potentially had a leaky float valve, might want to think about replacing them if you continue to have leaks.
My fuel Tee leaked at a gouge that somehow got there at the o-ring- I found comparable SAE viton orings for the fuel tees, float bowl gasket and the upper plenum gasket.
I was not able to get a 010 oring to fit on the air tee rail orings, just too large.
I think the metric oring that would fit there would be a M1.8X6, I just reused the ones on there since it would only carry air.

 

Here is the link,there are many pictures of installation. I hope it helps and do not over think it.

Thanks for all the tips. The one part I did not clean when I had the carbs apart was the seat for the float needles. If I have to pull the carbs again, they will be on the list. The amount of gas coming out makes me think that it was not just a small leak past a bad needle/seat, but instead the float not pushing the needle closed at all. I still do not quite understand why there is the elaborate system of tees and tubes to collect the vents for the four carbs into one, and then just vent it to air. Why not just leave the four vents separate? I am curious about it, as the o-rings for my vents seem not to seal anything, but I do not yet see if, or why, that should even matter.

 

Yeah, probably linked together to prevent negative pressure and other pressure differentials from affecting the air/fuel mixture.
