Fuel is overflowing in carb, 86 vt700
So i went and bought a 86 vt 700 and a friend suggested we remove the carbs and clean them because the bike was having a hard time starting and was popping when we did get it started. we put the carbs back on and hooked the vacuums wrong the fist time. we then did some research and we have the cables hooked up right now. the problem is we are getting a massive amount of fuel coming out of the overflow now. we drained the carbs and bought new plugs but fuel is still coming out of the overflow. The bike will not start. we checked the carbs again and everything looks fine. any info would be appreciated.
