Plugs Sooty (due to cold starts and short shunts never reaching running temp to burn off. Typical winter blues) and wire brush Sweep won't solve for long. Do you remember the old sandblast cabinets most garages had for cleaning spark plugs? The reason for sand blasting was to clean deep inside the plug body where a wire brush will not reach and clean all the carbon/soot off the centre insulator which was white porcelain as well as cleaning the contacts. Carbon is an excellent conductor and the spark can track down the outside of the centre contact to earth on the body of the plug rather than sparking between the exposed contact gaps when under compression. So sometimes checking the spark outside the cylinder can give a false impression all is well. Modern silicon carbide blasters are available quite cheap if you have a normal air compressor. This not only gets rid of any internal tracking problem but also makes it much easier to spot if the centre insulator has a crack. Want to see Mr Riley start first flick of the starter every time.
Yep you are totally correct sir, but having this car since 1987 l know how she performs, this time of year is always awkward for starting but after a good run there's no bother, so I'm not over concerned now, if this was mid summer l would just buy new plugs, the ones l cleaned are only 6 months old , Thank you for watching and cheers for the advice, ...
Sorry My Fault You were wire brushing the plugs and I said (to myself) "You mean !!** buy some new plugs" just as I said that you caught the wire brush in your jumper. In future I will keep my comments to my self quietly.

Thank you - any chance of a closer look at the fuel filler locking cap and fittings - I guess its been converted ??
No modifications to filler caps , just locking petrol caps, the one got stuck but is fine now
Sorry My Fault
