I have this '80 Honda Express II and it is running out of fuel in the carb bowl. I noticed there was little fuel flowing through the hose from the petcock to the carb so I replaced the petcock real quick. Same issue though. When the fuel line is taken off the petcock, fuel flows freely from the tank. As soon as I put the fuel line on the petcock, the flow is stopped. The line is empty, but it will not even fill with fuel. Just a very SLOW trickle.
The carb is cleaned out, didn't even look too bad. I believe the needle that stops the fuel flow into the bowl needs adjusted based on this issue, but the tab on the float is plastic and can't be bent a little to adjust.
Is there something I can do to get this fuel flowing better into the carb?
