I was going to ask about the oil from the exhaust. I guess you are just one step ahead of me

I finally got the thing to idle. in the CEN book it suggest the lsn to be "flush", so i was trying within one turn of flush. Now i have it closer to 2 turns in and it seems to be working better. I'm debating whether to go for the CEN .18 rebuild or going to a .18 OS. Do you guys think the OS is worth the extra money?
Thanks for the tips guys!!
