1996 model 345. Thankfully this model does not have that horrendous fuel shut-off solenoid on the carb. Do you think it would be beneficial to add a manual fuel shut off valve downstream of the fuel filter as close to the carburetor as practical? I have no flooding issues now. Still concerned about their history for fire.....although I did change out the fuel pump with the newer model with the routed drain hose. Thanks.
