OK, I had installed a new timing chain. Now the new tensioner extends very little and tightens it up; whereas on the old chain and new tensioner it was fully extended. What a difference! Tensioner and chain seem to be working correctly. However; I am still seemingly fighting timing isssues. Advancing it did NOT seem to cure the backfiring and engine miss. It starts right up though so I presume it is close or? I guess I will try DIFFERENT timing positions till maybe I hit upon the correct setup.

Scooter Update: To answer rks's earlier inquiry; after some research... yes I installed a 26mm carb on it and am using the stock airbox. I also installed a cheap high performance muffler on it, because the stock one had fallen apart. I am using a standard NGK spark plug, not the Iridium model. Engine running, but still missing. Plug inspection not showing black like when I first started repairs, shows common brown, but getting backfiring and hesitant throttle. The auto enricher is connected and now working as well. Any ideas?
