If engines are teched "AS RACED", why do they allow the carbon to be scraped from the piston?
BM, If you read the rule set scraping of carbon is allowed for measurement accuracy. Piston pop-up, depth of the combustion chamber, and deck surface are going to be areas cleaned to insure an accurate measurement point.
@@BriggsStrattonRacing I have read the rule set many times.
