Jon, if you don't mind doing that it would be great. I've got the Haynes manual and have even stood and stared at that for hours as well, but still to no availJake, mine had that problem too - I fixed that part by making a new lower hole for the lower mount of the guide channel (well, that's what Haynes call it).
I can take a photo if you like.
Hmmm, I'll do some searchingI'm sure someone posted a how to adjustment guide recently.
