Check that your .65 idle jet is actually sized correctly
God knows how many jets I've seen that have holes in them that don't match there markings
On cylinders 3 and 5 the idle jets may be actually larger than .65 mm dia hole
And that could cause an over rich condition on those 2 cylinders
That could explain the over rich smell and the cooler exhaust temps on 3 and 5
