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.
