I have posted 3 pics that show some levers Im not sure about- if anyone can help me please. The one on the exhaust manifold is ? The one on the fender is? And the two levers under the steering wheel- one is throttle and the other? Thanks.

I can see four levers in the first pic - throttle, gear, hand brake and power take off.

Second pic is the hot air flap valve for ensuring kerosene is well vapourised in the manifold by passing exhaust gas around the inlet section.

Third pic is the magneto ignition timing setting.

Your tractor must have been updated to the variable speed governor, that's why you have that type of throttle lever in the first picture.
The lever on the manifold changes the flow of exhaust. If you run it on gas, you put it in the open or cold position. To run other fuels like kerosene, tractor fuel, etc, you put it in the closed or hot position. This would help heat the fuel before it went into the engine to make it burn better.

The third picture is of the original throttle and spark advance lever. Throttle isn't needed because of the governor update and if the mag has been replace from the original, it has automatic spark advance and a spark retard built into the impulse.
Hope this helps.

Yes it does and thanks. So I did replace the carburetor and it is hooked to the lever that runs the linkage; so do I use this or the one on the fender? or both? The other is the spark advance; how do I know if the mag is updated or not? It is going to run on gas so I wont mess with the lever on the intake; looks like it must be stuck anyway. Thanks for your help.
