Not getting fuel - help

Hello Group,

I have a 1990 kawasaki vulcan 750. It was chattering so I did the Grembo trick to stop the cam chain from chattering and i can't tell if it worked or not because now the bike will not get fuel.

I crank it over and nothing. Pull out a spark plug and it's bone dry. I pulled the tank off the bike and checked the vacuum powered fuel shut off and it is working when I test it off the bike.

I put the tank back on the bike using hose clamps for the vacuum line so there would not be any leaks. And still the bike will not start. It is getting spark, but the spark plugs are bone dry.

I've checked that there is fuel in the tank, 3/4 full, and the petcock is on the on position - fyi.

Does anyone have any suggestions for me?: mad:

Have you checked to see if there is fuel in the carb bowls?

No, if there is what would that mean? If there is not then what would that mean?

Is the vaccuum hose to the petcock in good condition. No crack or leaks.

If there is fuel in the bowl that would mean that the float and inlet are not stuck.....If there is no fuel in the bowl but fuel in the lines leading to the carbs would mean that the float is stuck closed and needs a good cleaning or replacement of the float assembly.

If no fuel in the lines leading to the carbs from the petcock would probably mean you have a bad vacuum line or the vacuum line is not connected to the correct locations
