My 160 Mustang that I rebuilt last year is running great but the revs do seem a little fast. Got a cheap tachometer and currently running around 4000 when full governed.
Want to get a couple of those brass washers to bring the speed down a bit but don't want to import from Aus.
Can anyone tell me the size of the washers so I can source here and that 2 will bring the speed down a couple of 100?
