Seems to run real well but it was sitting not used for three years carb maybe ?

Hi,
Does the engine slow significantly when the auger is engaged? That would point to a carb problem.

No it runs great even when its trying to push the snow out the chute the auger and impeller never slow down we have watched them both while going into snow

PS Anytime you opt for a non-OEM replacement, it is wise to ask for a Kevlar belt.
