I just replaced the carburetors in my 99 cbr600 f4 due to a large hole in the last one, and I’m pretty positive I put it all back in correctly, but now the bike won’t start. It turns over and I can hear a little bit of noise in the pipe as if it wants to start, but can’t. It runs when we put starter fluid or gas directly into the carb, but when I put gas directly into the fuel line, it doesn’t seem to be going through to the engine. Checked all the lines, not clogged, and the fuel pump seems to be sucking and blowing. Is there some kind of vacuum aspect I may be missing? Or anything that could explain this?
thanks

 

have you got the write on for the fuel tap to the carbs
