Auto parts store may be able to help.
A friend asked me to make up a batch a while back.
Start with spark plugs with thread types you may need,
Due to design differences some brands of spark plugs are less work than
others.
Hard part is cutting tapered thread for Zerk fitting.

Grease gun technique can free up a stuck piston OR crack open a cast
iron cylinder, It is a quick all or nothing method that may produce
desired or undesired results. It is usually obvious when a powerhead
is so badly corroded..not likely to respond well to grease gun technique
Grease gun works well with light to moderate stuck pistons….if two or
more pistons are stuck in multi cylinder motor.it usually had not ended
well for me.
It is best to have several alternative techniques and the wisdom and
patience to use that which offers the best chance of a good outcome
not just fast results.
