Finaly found my pic I took of the timing gears after I put em in. I just noticed that the dots didn't want to line up so I got it as close as I could??

With the crank rotated just ccw a little, the dots will be more in line, so that is right on.

If you were to straight-edge the camshaft centerline to crankshaft centerline, the dots would align - the tooth off-set is due to idler-gear mesh, or lash

Now, check idler-shaft to timing-cover clearance, and yer good to go.

White smoke is normal for winter temps, but the IP may be retarded a little, or the advance mech is faulty.
