The car runs fine except the occasional idle-stall when rolling slow with the clutch ingaged. Also, wouldn't leaky O ring mean a hard start when cold?
I have blackened tail pipes and I was told by others that smelling fuel in the oil means you are running too rich and risking premature engine wear since the fuel is washing too much oil off the cylinder walls. I plan to dyno the car to determine just how rich it is, and perhaps install a AFC and get it tuned.
