I have a 53 SA that my grand dad bought new. I have been riding this tractor since pre-school. I only remember it being run on gas. Now that it has been passed to me and I begin to study it a bit closer as I make repairs I notice that the 2 carburetors I have are as described on page 29 of the owners manual. They have a main jet adjustment screw and a drain cock. I do not know the serial number of the tractor since the seat has been replaced. The engine serial number is FAAM 329352 G. Is there a difference in the gas and kerosene engines or just external accessories?
