The proper mixture for that motor is 50:1. Approximately 2.56 oz. of oil to 1 gallon of gas.......5.12 oz. of oil to 2 gallons of gas....etc..
The 4WF69B model, 4hp Johnson, would be a 1969 year model.
1969.
It is a 2-cycle 4HP Briggs motor.
The recommended plug gap for the 2000 model, 4 hp Johnson is .030 in.
A ratio of 50:1 would be required, this is roughly one pint of 2 cycle oil, to six gallons of fuel.
The proper spark plug for 4hp Briggs & Stratton is a J8 which I use in all my motors.
