Hello again,
I finally had time to check out the bike and did two things- drained the factory oil ( it seems it was grossly over filled and looked old to me when i drained it)then used fresh oil, re-filled with bike level to get correct amount in crankcase. Then I ran the air /fuel all the way in and backed out one and a half turns. Fired it up with full choke and when warmed up; i pushed the choke in and bike stayed running purring away 
Thanks to congpay and kutlassboys for their helpful input, I am looking forward to riding my Zongshen any chance I get
