I made an error.  I removed the pulley from my eccentric shaft.  I turned the engine over with the electric starter just for testing. Then I noticed there are timing marks on the pulley. Was I smart enough to mark the shaft and pulley so I could put it back in the same position?  Of course not.   Is there a simple method of reinstalling the pulley so the timing marks are correct, or do I have to take the engine all apart to fix this? My luck says I probably have to do a complete tear-down to determine the pulley orientation.  Thanks for your replies and advice. Paul, the idiot Conner
