You would need to find a similar type that is still available. Then go through the parts list to see what the actual difference is, i.e., jetting may be the the only difference. This is easily switchable.The latest P/N for the replacement carburetor on the FH601V-BS06 engine is 15003-7020. It is no longer available. Are any of the other currently available carburetors compatible with the FH601V-BS06 engine? Possibly with modification? Any other possible solution?

The last JD Kawasaki mounted FX850V-BS13 carburetor I did would have cost the customer over $600 which I instead installed a bushing and saved the customer over $450 when the choke shaft wore through taking out the
The solenoid would have no effect. All the solenoid does is prevent fuel from being drawn through the emulsion tube which helps to prevent afterfire when the engine is stopped.

I did replace the float and float valve last season. It did not fix the problem. I suspect the fuel shutoff solenoid may be defective or possibly a dirty solenoid seat? This season I have begun to get a wondering idle.
