My Oliver 1550 has been running great this summer. I rebuilt the carburetor and in order to accelerate without stumbling, I have to have the load screw opened 4 turns. I pulled the spark plugs and this is what they all look like. According to the pictures I have seen, its running too rich, but If I close the load screw even 1/2 turn, it stumbles on acceleration unless I pull the choke out a little. I dont have any heavy loads to put it under to work it, but hopefully there will be some plow days coming up that I can work it some. It has Autolite 386 plugs set at.025 per the operator manual. I havent taken time to run a compression test yet. Is this normal for a non working tractor?
