So the bolt that was broke was a specialty item called a dowel bolt. And honda is fresh out of them so I made a replacement at work and drilled it for safety wire. Here is a pic of the finished product all patched back together. And then a pic of the engine buttoned up and ready to go back in the bike.

More woes
Replaced the dowel pin on the ignition advance and got the bike running only to hear a noisier then expected clicking from the valves. Bad valve gaps? Lack of lube? Nope. I cracked the valve cover and peaked underneath to discover one of the cam sprocket bolts had broken. Back out the motor comes.

Advanced ignition
Worked on the CB350 a bit. It ran directly after the engine rebuild, then started backfiring and popping through the carbs. Reset timing a few times with points and such with no luck. Finally traced the problem to a 3mm dowel pin that keeps the mechanical spark advancer in place. It was too short and had slid out. A quick visit to the local shops quickly proved futile as "were americans dammit and we only keep standard hardware on hand". Sigh. Got an order off to mcmaster so should see my new dowel pins soon. Here is a pic I took of the mechanical advancer. Kinda cool.
