[Fot] pop up pistons for the TR2-4 engine ? RE: TR3 Race pistons and liners

[Paul Ricco]

As a very good industrial trainer once told me while I was being certified to work with products that his company manufactures, 

“There has been millions of dollars in research spent to develop the products that we engineer and sell.  They all work perfectly if you follow the directions provided with them.  However, most people do not follow the directions and they get less than ideal results”

So in short I have learned that there are a lot of good approaches, if they are executed properly and the owner is happy with the path chosen.
