The customer picked up the engine today..

He will do some heat cycles tomorrow and race tomorrow evening
Jason and I will go down there and see how he does.

Well... The top end is torched... Disassembled and found a plugged pilot jet

I know I know, that's racing... But I don't have to like it.
So, rebuilding the top end. The next race is in two weeks...
