Thanks Jack and Pete,

yes did my apprenticeship on Fiat vehicles, and Dad was a dealer for 30+ years.

Still own a couple of X19's, and had a 130 sedan for a while about 20 years ago.

Problem I actually have with the SB38 is no spark from the 60112 B&S engine, and I can't see any sort of kill switch wiring... but figure I've got the ignition earthing somewhere between the magneto/coil and the plug, any ideas whereto begin looking (I like to consult a manual before simply tearing things apart.)
