I made a separate post about how the engine is running. New spark plugs may have cured that problem. I will know for sure when I can run it under load. But, I disconnected some hoses, while troubleshooting. I took photos of the hose connections before disconnecting the hoses. But, the photos didn't capture everything. I am confused about the balance tube manifold hoses. The starboard side hose goes in to a hose nipple that is in the crankcase. But, I am not sure where the port side balancer tube is connected to. It looks like it was routed either to a "T", or to the air silencer. I do not understand why the port side balancer tube would go to a different place than the starboard side balancer tube.The factory manual has diagrams for the oil recirculation system hoses.----And for the electric fuel primer valve hoses.----I do not believe there are " vacuum " hoses.-----What is your motor doing / not doing??----What trouble shooting has been done if any ?
