Uno constent misfire

[mia1100]

Hello to all.

I have a mia 1.1 running with a constent misfire.
I have changed plugs and checked that all plugs are sparking.

If i pull the ht lead on the third cylinder there is no change.
What could be the problem?

Your help would be appriciated as i cant figure this out.

Obviously third lead or spark plug.
