Fleetwin,
These are all good points. I did remove and clean the Hi,Mid and low speed jets except for the bottom carb as one of the ears was missing on the hi speed and a screw driver could not turn it. With a small wire and light it appeared as clean as the other two. I will try a different tank/fuel line and check the solenoids action. Are your thoughts that one or more cylinder isn’t getting enough fuel for some reason? The clear plastic disposable fuel filter I put in between the carburetors and original fuel pump/filter show a flow when it’s running
