Welcome. What you have going on there sounds like it's four stroking. It is normal for this design to four stroke at cruise, and is especially noticeable until the engine gets a few hundred miles on it.

Have a look at your plug, and if it is really black and oily, then you'll need to make a couple of small changes.

Use a break in mixture of 24:1 at the very lowest! Do not use a 16:1 mixture.
 
nice to be ear its been run in and been runnin 25:1 plug is fine fuel clean , dose the same most of the time when cold thats labour a bit,wonder about CDI unit cheep to repplace one prob sorted, but as ya say aint broke!
