How to set gas when starting my Ford 9N

Anonymous-0 · Jul 10, 2012

I have a 1939 9N Ford tractor. It runs fairly good, but recently I seem to be flooding it a lot when starting it cold. How should I set the throttle and choke when first starting? Also, yesterday I not only flooded it but there was some gas dripping out the bottom of the carb. Perhaps one of the drain plus is loose. I will check them. Anyway, a neighbor told me to set the throttle at about 1/2 and pull the choke all the way out. Does this sound right? Any advice would be greatly appreciated. Thanks.

No one engine will start the same as another one will. Many things come into play as for flooding. #1 a clogged up air cleaner will cause that. When was the last time you checked and cleaned it and change the oil?? Most engines if tuned correctly will start with little or no choking. On my 8N I set the throttle almost wide open and I do not touch the choke and it starts right up most of the time

personaly i never use the choke unless its needed.my starting procedure is set throttle about half way ,start cranking ,and if it doesnt bust right off then i pull choke and shove it right back in.I do the same cold or hot winter or summer.two will bust off every time with no choke,one will start as described above,the other is taken apart so i cant say.but they should start with very little choke in my opinion.I would say it depends largely on your tractor,but i always start with no choke and apply it only if needed.my opinion of course.

I agree with old, every gas engine has it's own way. My Jubilee likes an idle, choke it while cranking and after 4 cranks get off the starter and it usually starts.

My IHC and a 10 hp mower likes an idle and no choke.

Have a briggs that likes full throttle and full choke.

A 13 hp honda likes full choke and idle.

20 hp kohler likes fast idle and choke after the 3rd crank and get off the choke on the 4th crank or it will flood.

Like old said, find out what your tractor likes...lol.

Ours always started at about 1/3 throttle, start cranking and pull the choke out, then push right back in, on about the second revolution, and away she'd go. Ran that 8N for about 20 years, and it always started the same.

Leaving the choke pulled out will flood it in short order.

I think it's very common for a little gas to drip out when you choke them, with an updraft carburetor that doesn't necessarily flood them. Our Farmall C starts best 1/3 throttle and no choke, but as soon as it starts then it needs 1/2 choke for 10 seconds. How the carburetor is adjusted has a big effect on how to start them.

Thanks to all. Great advice and things I will try. And thanks for reminding me to check things like air filter. I am fairly certain it needs servicing. I have never touched the carb, but may check the settings. I recently put a little carb cleaner in the gas and hope I didn't screw up anything. Thanks again.

Agree. On my 8N I just flick out the choke for half a second. Fires right up.

Putting carb cleaner in it might of cleaned out some orifices so it is getting a little more gas. As carburetors varnish up it's common to have to open up the adjusting screws occasionally.

set gas just above an idle.

crank and pull out choke to full then to half, then to full and then to half till it fires off. move choke to where it runs best... let it run a bit and keep easing in the choke as it warms up.

when warm....

its and updraft carb, so it will always need a quick pull on the choke to start, even when warm. but just a quick pull and then back to open.. repeat till it fires up.
