Loose Spark Plug

[a2zworks]

Hi all,
Why could it be that every time I check spark plugs one is loose.

If you fit new plugs does it do the same thing again?

Yes, put new plugs in last Sunday checked yesterday and left plug was like just finger tight.

Do you torque them down? Not that I think that is hugely important but you would know they were all the same

Check the thread on the cylinder.

I don't torque the plugs, just go by feel, will try torquing and see if this helps.

I shall check the thread on the head and see.

Thanks for the feedback chaps.
