How do you adjust a spark plug ?

[Joris]

My brothers cossie is misfiring, as the plugs are at 0.75mm
it should be at 0.65 mm or summat ? (3dr cossie, 330 conversion)
Plugs are AGPR 701.
I have measuring plates, but how do you adjust the plug ? Do you just knock it against the wall ???

i prefer the kerb or a nice big pavement slab, just a slight downward tap gives you that more precise adjustment and control

Gentle taps against a solid item. I use a vice, something that is solid but non-abrasive

If you remove the timing belt, spin it over a few times, that`ll some times reduce the gap for you...
Only joking m8.....
Its allready been answered for ya..Gentle taps against a vice or the concrete floor.

0.25 SHOULD BE THE GAP USE A FELLA GUAGE OF THIS SIZE BETWEEN THE ELECTROD AND GE IT A GOOD TAP
