Now have a somewhat larger and fan cooled one more designed for the

I guess you cant use one of these on modern vehicles:

The good old spark plug inflator... remove a plug, screw the inflator
end in it's place, connect schrader valve to tyre, start engine and it
chuggs away on 3 cylinders (or 5, or 7 as they were a yank invention i
believe) inflating the tyre.

Apparently still used by the off road guys running simple engines in
dune buggies and sand rails, but a modern engine would go into limp home
mode and prolly not fire that cylinder again after the plug has been put
back in, whether it'd be injecting fuel whilst inflating i dunno, but if
it did then a fecked cat can be expected as well.

Probably not going to work terribly well on a diesel Disco or van,
either...

Nor single cylinder motorbikes for some reason
