this is another question about my 1967 sears 4hp model 574-59660...my question is this...I know this is an air cooled engine but it does have a water cooled exhaust...im wonder how i can tell if my impeller for the exhaust cooling system is working right....when i run the motor i can see and feel with my hand that im getting water out of the exhaust....almost like a hard mist...but im not sure how much should be coming out...otherwise the motor seems to be running ok...any advise would be great...thanks PS....does anyone know where i can get a replacement propeller...ive looked everywhere online like ebay and stuff but no luck
