Socket to Fit CJ6Y Spark Plug.

[Deleted Member 4613]

I need to remove the spark plug from the Tanaka Purefire 3300 which has a CJ6Y
plug. I have about 7 sockets and none fit. And I'm having trouble finding out
what size socket fits this plug. Does anyone know?

There are 4 sizes I know of 5/8", 13/16", 19mm and 21mm.

I think it might be the 19mm.

 

[weefek]

get some digital calipers from a local autochina store ?

I think it might be the 19mm.

Some of those small engine plug wrenches that are supplied with a motor has a different plug size on opposite ends, one end fits the plug and the other who knows. Funny thing is there is no indication on what size either are. I have a 63cc hobby motor that came with one of those wrenches.

The 19mm I bought fits.
