Off Idle Flat Spot
I've been an i6 engine lover since the early 1960's and I wish this one wasn't so far away .
I've been able to make clapped out InLine engines with 60# compression run very well .
This one clearly has some internal issues but, judging by the spark plugs it's running way too rich, apart from the oil wetted # 2 one .
There's a bit of art to tuning the InLine engine, I think perhaps he still has some sort of vacuum leak .
