Grandad Dave, Tee Hee.
(I'll see if I can dig it out and photocopy it for you, I just can't remember if it was in Karting mag or the MSA rag. I thought you had already seen it.)
They did comparisons between the 'new' digital burette and the old science lab school jobby and found glaring differences.
The old Greek meniscus coming into effect and the oil clinging to the burette surface.
You can conclude that drivers who have had their engines checked in the past, were probably on the button or below but got excluded anyway.
I also think that on a wet meeting, drivers should be allowed to wipe the head and piston first so that any excess oil and soft carbon can be removed.
Depending on what brand of oil you use, you can get a build up from a slow running engine due to maybe waved yellows or battenbergs just before the race end.
The diy'er will now find it impossible to be sure that they have the correct head volume if they set it with a standard burette and then get tested with a digital burette.
i would have thought that if you get tested and have set your volume with a standard burette, you should be allowed to have it measured with a standard burette.
If you purchased the standard burette from Tal-ko, then would it not be reasonable to ask that you have the head volume tested with that same burette in scrutineering.
Or are we saying that the equipment that is supplied, is appalingly inaccurate, hence the change to a digital instrument.
Whichever way, exclusions have been given out to legal engines due to inaccurate proceedures and wins taken away from drivers.
