I am getting fuel to my fuel pump and not to my carburetors. I have taken the carbs out multiple times to double check them, and they seem right. I have been looking for a better diagram or picture of the carbs and how they connect to make sure everything is right. I have the manual and according to it, its all ok.

Any advice as I gotta get this thing running asap.

Thanks!

I am getting fuel out of the fuel pump, it is actually coming out of the fuel line that goes into the carbs. Just nothing entering the carbs at all. I have check every line and there is no blockage. I am just lost at this point.

Check your spark plugs to see if you smell gas. Are you getting spark too?



Your description of the issue is not very detailed.



explain why you think it is the carbs and what is the exact problem you are concerned about. I am assuming the bike won't start. If so, is your engine start button on or working correctly? That is a serious question btw...

No fuel in all four carbs. I am not so sure I have all the lines connected properly. I got looking at a picture I found on this site of a same year, carb and I am not so sure I have them correct. If you can see this picture where does or should the fuel line connect?

This is the picture I found. What is the red line connecting to? If this is the fuel line, mine does not connect there, it connects directly into the emission control.

Could there be something wrong with the anti after burn valve or the slow air cutoff valve?


It is almost like something is not letting the fuel be sucked into the carbs. The fuel comes all the way up to the carbs and then stops.

Not a 1200 expert but I believe the black hose at the bottom of the picture that Ts to both sides is the fuel line.

What is the red "line" running downward at the bottom of the picture.

Okay. Fuel is coming into the fuel lines, but not going into the carbs.
Floats and needles are all brand new and replaced today.
All lines seem to be connected properly. When I disconnect a fuel line and attmept to start the bike, fuel comes out of the line, just does not go into the carbs at all. Not even a drop.
Spark plugs are brand new.

Thats my issue. Something is causing the fuel to not be "sucked" into the carbs.

take float bowls off bottom of carb, put a FILTERED source of fuel onto black fuel lines, squirt gas in - you should see it coming out of 4 places

if not then you have blockage internally on left and/or right fuel lines

did you clean the filter "socks" on top of the float valve seat? if you had enough crap come through prior to cleaning/rebuilding it could collect at the small filter above the brass seats and block off the individual valves - this would be rare, but could happen if the inlet filter was missing/damaged

I have seen dirt dauber wasps build nests in open fuel lines left in an open garage - any chance these sat outside with open lines?

btw, the red line appears to be the vacuum line to the overrun valve - must be connected to the "T" up above the carbs

Fuel does not get "sucked" into the carbs, it is pushed in by the fuel pump. Have you loosened the bowl drains to check for fuel in the bowls?
I'll meet you in the chat room if you wish.
