HI all,,

changed my plugs at the annual this year (chinese to chinese) and we now have a vibration at high rpms.

In keeping with the previous discussion of vibration, I'd like to check the gaps.

I know the gap specs (from the book), but what massive electrode tool would I use to fix them if they are out?

I've looked at ATS and aircraft spruce for a gapper, but they are all 18mm?

thanks

Mike

Mike,In every can of Chinese DZ5 plugs there are 10 plugs, copper gasket/seals and a gapping tool, this is a go/no go "feeler gauge" type tool.  No need to buy any special tools.
Always Yakin,
Doug

I'm pretty sure if you buy 20 Chinese spark plugs from Doug, the sealed container with the plugs has a neat little gapping tool in it. Check with Doug to see if this gapping tool is available separately.

Hi guys,,

yes the go no go tool is there. I'm not terribly familiar with its use (used to gappers), and as such didn't want to risk bending/breaking an electrode/other.

I understand the gap tool slides down next to the electrode to test the gap,and it should be tight, but easily slide up and down. However if there are instances where the gap is too tight, can the tool be used to bend the plug back?

If it is too tight just tap it in and it will set the correct gap.

Doug & Mike:

NO!!!
That is not a gapping tool. It is simply a gauge. Do not attempt to change
the gap by applying any pressure to the center electrode. This can crack the
porcelain insulator.
