well weather has been getting colder..
and now when i go to start the truck in the am it starts right up. but smokes when cold... even more if i give it gas...
then goes away when it warms up .. no antifreeze in oil.. not lossing antifreeze i know these trucks are known from headgaskets.. i dont think thats it.. looks like a new carb on the truck maybe just not ajusted correctly?

ive seen this tread


maybe just worried about nothing major? does seen to eat some gas up quick

Keep an eye on your oil (like that needs to be said...lol) most likely valve guide seals...
