The pump on my OM617 is set to 26 right now, I know 24 is the stock. It seems to idle faster now, I adjusted it slower via the length of the throttle linkage. My startups shake more and there is even a lil sputter but as soon as the car gets down the block it becomes a calm, striding W123. Its faster and still smokeless.. but should I have kept it at 24? Can someone tell me the differences? Am I burning more fuel & am I stressing out my engine? Or the opposite?
