G'day... It is a simple case of lulling you into a false sense of security. It knows!!! No, not really. This engine in its standard form will still run pretty well despite neglect and mal adjustment. This is why when set up to perfection the performance can be absolutely phenomenal. They really can move in mysterious ways, defying all logic. Treat it gently as you start to learn its foibles, reckon you have a winner there.
Just checked the wear pattern on an ATD gear...the mesh pattern is almost to the bottom of the fibre teeth, so either you have a bad or worn gear, or the maggy is fitted a bit too far back. The depth of mesh is acceptable for light local use, but not really reliable enough for highway trips. Try slackening the three retaining nuts and see if you can move the maggy a bit closer. The fibre gear is replaceable, fiddly to do. You need one with 44 Teeth if you go searching for another ATD.
Bergs, just heard from the pub...red carpet awaits. I am booking an eye test tomorrow.
