Hello!
i have a 1977 Honda CVCC, 1.5L, 4-speed manual transmission. It generally has run fine for a very long time, but suddenly a strange fuel supply issue has happened.
it has a rebuilt carb, new electric fuel pump, new oil pressure sensor. The issue, is that the fuel pump will start pumping fuel ultra fast, like I am full throttle up a hill, and not stop, and the engine floods.
There is also fuel coming out of the primary needle valve when this is happening.
the fuel cut-off solenoids on the carb are functioning. I have tried adjusting the needle valves, idle adjust… nothing seems to make any significant change to the strange fuel pump issue.
any ideas would be much appreciated!
