This is a VERY interesting motor. It has various hoses running around that I am trying to make sense of.
In particular…..there is a part of the carburetor (accelerator pump according to Parts Diagram) that has coolant hoses hooked to it. One of the hoses is the "telltale" overboard hose.
Can someone explain the theory and/or provide me with a diagram of the coolant flow on these engines? For example; why are coolant hoses connected to the carburetor?
The first picture shows the carburetor; the hose exiting on the left is the telltale. The hose entering on the right goes to a fitting at the bottom of the powerhead.
The thin arrow is the Telltale hose. The thicker arrows show the path of the inlet hose.
The part circled on the diagram is labeled as an accelerator pump.
This last image shows the larger hose that runs from the thermostat housing down to a fitting on the mid-section.
