09/04/15. A sunny day meant that I took the governor housing outside in an attempt to remove the governor weights. I used my new parallel / taper punch set to try to remove the taper pin holding the gear onto the governor shaft. After several hefty whacks with a hammer, it did not want to move. So I resorted to drilling it out. However, after drilling around 3-4mm, I decided to try again with the punch and hey presto, out it popped! I was then able to remove the shaft from the governor housing and completely dismantle all of the components. I have ordered a new set of 700rpm governor springs, which I will fit when I reassemble everything.
