I put this rebuilt motor in & replaced my old head after having it serviced in 2024. Replaced the clutch too. It has 600 miles on it and still smokes when I first crank up or pat the gas.
It has sat up for the past 6 months while I worked on the sunken cab & foot / floorboard.
Cranked up & ran until warm today. I’d say the smoke was grayish & it initially smoked a lot.
So the rings should be seated by now. The head was serviced.
What could be wrong or what can I do? Bad head?
I know it has the wrong carburetor but that should not cause what I see??
