bit smokey...

I started my gordini for first time today since start of September and when I took choke off and it was almost warm I noticed a lot of grey white smoke out the back even more when I pressed the gas but it was idling a Tad bit lumpy but nothing out the ordinary..

What could this be? Could it be the fact it needs a blow out as I have been told that full stainless exhausts smoke a bit from cold anyways? Iv notice a puddle of unburnt fuel in the exhaust also..

Is it something I need to worry about?
