Welcome to Just Answer, I will do my best to help you solve your problem

Rickheatdoc :

That "smoke" is probably the fuel mist coming from the nozzle. The most likely culprit would be a faulty ignition transformer since you seem to have covered the other bases

Customer: That makes sense, forgot to mention the smoke came out also mixed with smoke rings
Rickheatdoc :

a weak transformer is still my prime suspect

Customer: thanks will replace. I am accepting answer.
