Don, took me about 1 1/2 hours start to finish. It is not that difficult, and the timing marks are fairly visible with my "cheater" glasses and a small flashlight. Biggest issue I had is that I left the rad on and had to fit my big ham hands in the tight quarters.
Once the mag drive gears are timed, just make sure that #1 cylinder is on TDC, then place the mag on. Pretty much it. Like I said before, with the H4 mag, you can only be in 1 of 2 timing locations........dead on or 180 degrees out.
There are a few degrees of adjustment on the mag, which if you roll it as far as it will go "away" from the block, while on tdc, then slowly roll towards the block, the impulse should trip. Back up 1-2 degrees, and tighten her down. If you ever plan to crank the old girl, that should be exactly where you need to be.
Once again, feel free to call me. Send a PM or email for my phone number.
