150cc Timing Chain Crankshaft Sprocket

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.
