Hi artxty,
Before you do anything do you have any history on the motor, always a gamble to throw money at these and then you find the motor is no good. One of the big problems is the governor has failed and that opens up a new can of worms. There is a work around that problem which I have done a number of times but does require some fabrication skills. Another option I have used is fitting a motorbike carby but that also requires some skills
Anyway here is a carby, should fit but as usual they can require some mods
