Terro - this may well have solved my problem these diagrams!... could you tell me if the hose from the bottom of the oil tank is supposed to connect to number 3 ?
does the oil tank connect to the oil pump and then to the carb, or does it go from the oil tank directly to the carb ?
so the thicker pipe comes off the oil tank into the waterpump part/magneto.. and then goes into the oil pump and into the smaller thinner pipe going to the carb.. is that right ?
