Here is a cheap 345 for what it is. I see the crank, case, flywheel, oiler, ignition are there. It is so dirty I can not say if it is all good or not but don't see obvious defects. $20 plus shipping. It will fit in a large flat rate box so call it $41.00 total. Might be good to make a "poor mans" 346 if you have other parts.
