Re: LOW ENGINE RPMS ON YANMAR 75

Ben,

 

For the RPM - something super simple to check first - have you disconnected the throttle cable and checked the revs by directly operating the lever on the fuel pump? Without any other symptoms maybe your throttle cable has gradually become badly adjusted.

The cold running might be due to someone having removed the thermostat or the thermostat not working,
