On the way home from SWR, not far out of town, something went wrong with Henry.
First i thought its the exhaust because Henry sounded like a world rally car
but after i stopped and had a look it turned out that we had burst the spark plug.
We turned back to our friends and because it was Sunday and all
the shops were closed we had to spend one more day in SWR.
On Monday morning we bought a new spark plug and the
guys from the garage lent us the tools for getting the old one out
and the new one in.
After 15 min. everything was sorted an we could head off back home.
