of the Wr. Neustadt cross track.
Picked up Junior from school, and then directly to the track.
Empty, perfect  😉
Bad surprise: His SX engine stutters bad. But, after my long technical fight with the EXC, shorthand action: Spark plug removed, cleaned, reinstalled, works! Perfect!

After this short show stopper, we did chase ourselves over the track, as it happened, sometimes we were a little bit to fast for the tables, leading in a little bit bigger jumps then last time, but still not whole tables…

As Juniors spark plug did foul at the beginning I checked mine afterwards.

In my opinion, perfect picture of  spark plug!

As it seems, through my crusade with my lot, I have advanced to an carburetor expert . Or, so…..  :-0
