The important thing is that it is running good.

I've had some that were touchy on the needles and would send out confusing signals.

There have been times that I had to touch up the needles on three or four outings before the tuning settled down for me.

But any time there is a big temperature change you will likely need to change the needles some.

A sudden real cold spell will make the engine suddenly lean and a summer like day in the winter will suddenly make the engine rich.

Enjoy.
