New Carb adjustment

pj1957 · Jun 11, 2019

I just installed a new sediment bowl and carburetor on my 9N. The tractor starts and runs with the choke partially closed, as soon as it it full open the tractor will stall out. Sounds as if it is leaning out. Was to have been adjusted prior to shipping? Any adjustment advice ?

Set both screws at 1.50 turns out. Or just turn the larger screw on the front out until it runs without the choke and a little more out.

Roger in Iowa, thank you for your knowledge sharing.

The 1.50 out is a starting point. Probably will have to go out some from there.

Setting at the factory is a farce!

Carburetors cannot be factory adjusted but must be adjusted to the engine upon which installed.

Others have suggested starting at about 1 1/2 turns from seated. That should get things going unless something else is wrong.

What type of fuel are you using
I have a Ferguson TO-30

I switched my fuel from ethanol fuel to non ethanol and had to re adj the carb.

and what a big diff in the way it runs more power and it starts so easy now.
