Its not a lot no, plus it could just be left overs from the old engine... I dunno.
When i aired to atmosphere on the old engine it created bellows of smoke (you may remember my thread?) and then the engine decided to fill with mayo. It may just be a coincidence, but it all started going wrong from blocking the metering head and fitting a little filter to the breather tank.... I'll get it booked in somewhere to take a look early next week anyways
