I understand how the prime works and the on setting. When it is on and I turn the motor over it pumps fuel via the diaphragm pump that is built into the pet cock.
I may just leave it to the on position and try startign it and that could indicate an issue with the pump and vacuum . but it seems to work well when I un hook the fuel line and turn key(turn the motor over)
I cannot figure it out. if i spray fuel into it it will run a bit
If I run it on choke it will idle but not run.
Could it be the Mass air flow sensor or some kind of electronic issue?
