We only idled ours for about 1min (just to warm it up) then straight on the track at about 90% race tune (we call it the honeymoon period for the first tank). Then over the next 3 -4 tanks we increase to full race tune.

Since then this engine has done 10 litres still has grreat compression at TDC, no slop on the conrod and between 9 - 10 min runtimes from a buggy.
