I'm well aware of the principles of blueprinting and while I agree that it is better than parts selecting, it's not the answer in itself. Partly because of the time restraints involved in checking engines, especially four strokes. Many of the problems relate to castings of ports and crank webs etc. which are inherently difficult to measure and once factory finishes are removed, you open a whole new can of worms.
The answer perhaps should be in dedicated understressed kart engines with aircraft level tolerences from new. Factory or single supplier (non-interested party) sealed. I gather that TKM 4T & 2T, come close to this. But this doesn't help Cadets. With such engines for major championships, engines could and should then be pooled, to add another level of egality.
The advantages for karting and British motorsport would be enormous. For the first time it would be possible to look for and encourage talented drivers from all levels of income & influence, rather than just the well heeled & well connected. How many more people would compete in big championships if they knew the good engine scenario was out of the equation. Driver training and motivation would also improve enormously, when the 'he's got a better engine' excuse is removed.
