Have replaced supply lines and fuel tank. Machine wouldn’t start. Has spark at plug. Machine starts If plug removed gas placed directly in cylinder but doesn’t seem to be drawing from tank. Could supply lines be reversed?

Yes, if the Blue Max 52623 starts when gas is directly placed in the cylinder but not from the tank, the supply lines could be reversed. This could prevent fuel from properly reaching the carburetor. Checking the fuel lines for correct routing and ensuring they are properly connected can help resolve the issue.
