i've got a newly rebuilt engine (old case and pistons, but i think most of the rest of it is new [new rings, push rods, valves, etc.]) and i've changed the oil two times since the rebuild which was about 600 miles and 4 months ago. noticed with this oil change that there was a gas smell in the oil and that the oil didn't look or feel right either. is this a normal symptom of a newly built engine or did something go wrong? also, put on a new carb recently and i can't say that i'm the best at tuning those things so does that have anything to do with it?
