hi the chrome will be ok to steelwool them with some metal polish you will be suprised.

There is no real way to see if the insulator is bad without disassembling the plug. Yes deep inside the metal the plug ceramic insulator can be cracked. I have done this just to prove to myself what I was thinking was happening on some engine where the plug would fire outside the compression zone but not when under compression load.

Of course this will destroy the plug. Just easier to test with a known good plug. Even new plug can be bad right of the box. And just accept the results especially under shop conditions where time wasted is not good for the bottom line. When shop rates are around $65 or higher a $3 plug can cost a lot more.

But during quite times learning what was the problem does help in future troubleshooting. Here the 10mm NGK CMR6 plug has such a high failure rate that I replace them with Bosch plugs which rarely see a failure with.

CJay,
I wouldn't get too fussed about a wave washer in there, any spacer that will fit over the bolt will be good enough, you only want to take the slop out of it

Hi Bevan,

Looks like a 3G Villiers 70cc 2 stroke from the fifties.

There should be a crank case stamping ??? X ?????? see pic below , that number usually tells you what mower the engine was for.

And we would need to know where in this wide brown land you would be because postage on these things is cost prohibitive

Hi All,

Sorry for taking so long to reply - and thank you for your suggestions and photos.

@Tyler - Yep thank you for that, after some research and just a touch prior to your post - I did manage to find Wayne from Cylinder Mowers WA in Mandurah.

He is amazing and an absolute top bloke - new bolts received from him.

So for anyone that needs Alroh parts, he is your go to - reasonable prices, and they arrived quickly too.

Thanks NormK, great to know, will give that a shot!

The mower has now been painted and put on display.
