Which engine have you got?... There were several fitted, though I expect it's a *** 4/3. If it is then it should be fitted with a Champion L10, The NGK B6HS or Champion L86C which are modern equivalents should also work and are easy to find if you don't value "originality"

A champion plug 12jyc what moter will it fit in

plugs for 350 block , 4 barrel carby 1967-19710 is j12yc
all plug descriptions have a series of letters number and can download the champion chart from the champion plug site
it works like--- this any plug that will screw in the hole will provide a spark
you have to measure the thread length in the head as the plug thread cannot be longer or shorter that that length
next the sealing is by taper or copper gasket so the plug will require the same as is in the head ( flat or taper ) whether the electrode protrudes or not depends on the application ( High speed engine etc)
there are factors that come into it as well like the heat range ---cold plugs for new engines and hot plugs for worn engines to burn the oil

What is the difference between Champion RCJ7Y and CJ7Y Champion spark plugs. The first one is the recommended one for Poulan 4218AVX. Are there any other spark plugs available for this model?

The RCJ7Y is a resistor plug and CJ7Y is a non resistor plug. Other makes of the same plug are.
Bosch = WSR5F
Autolite = 2974
NGK = BPMR7A or BPMR7Y and 4626

You could use the CJ7Y but really need to fit a resistor type spark plug cap to the ignition lead.

The J8 spark plug is typically used on almost all small motors. You can google J8 cross reference for a list of alternatives that will work.
