This morning I was tidying, throwing out, from the cupboards in the garage. I found loads of things I have not used for years and some I have never used and probably never will.
Amongst the junk I found a 'Plugometer'. I think it must have belonged to my late uncle.
I believe you use it to compare the state of your spark plugs with the pictures.
There are a set of small feeler gauges and a tool (broken) for adjusting the gap.
I notice that Champion recommend plug changes every 10,000 miles.
Should be in a museum!
