RE: YS 170 DZ CDI
I probably should mention that I had to turn my new pump way out from flush as well, compared to the original pump which ran close to flush.
I'm still getting smoke on 10% oil but it's a touch rich as it's still breaking in from the latest rebuild.
Apereira, how often do you replace the plug? I wonder if trying to stretch out the plug life a bit makes it a bit sensitive with normal (20%) oil levels? I'm pretty cheap when it comes time to replacing the plug....
Cheers
