The VM 32's come up quite often on Ebay. You will need a different carb mounting (boot) as the 32 uses a smaller diameter one. If you are using the stock air silencer, it also has a different carb mount for the 32 vs 36. If you don't have the air silencer, start looking for one. It will affect performance if it isn't on there. Individual air cleaners let in more air and the jets will have to be changed to compensate for that.
