13/16” Master cylinder for the clutch?

[Wooly]

I currently have a ¾” master that is leaking and have a 13/16” with under an hour of use on it. Any issues going to the larger master for an external slave, factory style clutch on a MK9 equipped Formula Ford?

The first problem that comes to mind, is if you have a racing clutch (F-3,etc.), operation may become more like an off-on switch. The larger volume will move the slave faster and make it harder to ease into clutch engagement.
