So I spent a rainy day in Melbourne taking the chain off a soaking them in petrol, then scrubbing them with a toothbrush and re-lubing with Penrite chain oil. Worth thinking about where the overspray will go, because it's sticky and you'll cover your freshly cleaned frame. I had also noticed that as I adjusted the reel lower to get a good setting to the bed knife, the reel to intermediate drive chain became really tight , so I took the opportunity to set the reel where I wanted it, then adjust the chain tension. Took a bit of fiddling because you move up and down and back and forth at the same time. There's a great video on facebook of how to do a Scott Bonnar 45, and this is the same way.
