Plug Gaps?

[JamesArup]

Stupid question .... As usual

How exactly do you change the spark plug gap ... is it just a case of screwing it in more/less :?:

Any suggestions for me (running 1.0-1.1 bar at 300+ bhp)

Cheers, J 8)

Get some feeler gauges and find out what gap you want (most people here are going for 0.7mm) the gap is measured from the electrode to the other thingy :roll: if its to big bang it on the floor until its closed up enough or prise it up a little if its to small.

You can normally get little combined tools for checking the plug gap cleaning them and adjusting them. To change the gap, use the tool to lever the errrr....... top bit whatever it's called to either open it or close it. I suppose you could bang it on the floor :shock: but imo that's abit hit and miss when you're trying to set a gap to 1000th of an inch.
