1939 famrall H propane No Throttle response

I have a 1939 Farmall H that runs on propane. It starts OK. My problem is the ensign carb is wide open so propane just spews out the bottom. So I'm going through propane like crazy. I'm thinking of rigging a throttle cable to bottom of the carb. I'm however hesitant as this may not be the original way of doing this. So I'm stuck on one speed but spewing propane like crazy. If I close the carb at the very bottom slowly it revs faster, but if I close it all the way it chokes out and dies but does rev up sweetly. The throttle arm does absolutely nothing. I checked the governor to see if the spring was in there and it looked OK. I Will replace. Any advice on this issue is good advise. Thank you. I will post some pictures of the carb ASAP.
 
I don't know much about propane systems but the fact that propane "spews" out of the bottom, tells me something is VERY VERY WRONG with the carburetor.

The thing you're closing on the bottom seems like it might be the choke, which should be fully open when the tractor is running normally. It is only used for cold starting to richen the fuel mixture. Again I don't know much about propane systems so I am only guessing here.

Raw fuel should not be spewing from the carburetor, and closing the air intake is not the solution. That much I know.

Yep that's what I thought. Thanks for the post. Hence the reason I'm thinking of putting a throttle cable to the bottom of the carb. The spewing slows down as I close the choke and the engine revs up. I wonder if the governor becomes disabled when they converted to LP.
 
You need to find someone that knows what they are doing to fix your LP Gas system. Most likely both the carb and regulator will need to be rebuilt. Running it like that is an accident looking for a place to happen.

I'm all ears. I'm in Texas. If anyone knows of where I need to call. Id appreciate it much. Removing the parts is not that big a deal for me. I've been looking online for kits etc. and I cant find anything for ensign. Surely there's someone out there that knows. I even tried to contact Denys' carb shop no luck from them either. Last thing I need is for the tractor to blow up in my face. I used it this weekend with no throttle. Runs pretty good. Except no throttle and I went from a full forklift bottle of propane to a quarter of a tank in less than two hours..
 
I would ask your propane supplier. They should have connections to
folks with experience on all manner of propane equipment.

If you only knew. I love in a small country town. There is no propane supplier.. LOL I gota take a forklift tank to the city for fuel..
 

i know how you feel, im in e. texas and have to drive 50 miles in any direction just to get a steak dinner for me and the wife

bass
 
There is that guy from Oklahoma,he sold two way radio, and L.P. equipment,etc, he passed away but his wife is running it now, he was really good, If i was home i could look up the name and number! Anybody else know who i am talking about! Maybe it was Erberhart.[Last name]

id appreciate it if you could get me the info when you have time.
I'd like to send the parts to someone to rebuild them and repair them if possible. Or maybe they have kits? And I'd be willing to give it a gamble. Thanks
 
No, the governor is not disconnected. A tractor absolutely needs a governor or else it would not maintain a consistent RPM.

Don't waste your time with Denny's carb shop. I have never heard anything good about them if you have to interact with any people there.

Thanks for posting. So then I'm getting fooled by the choke and I need to look into governor linkages??
 
I can recommend a call to Matt at Motec Engineering in Tipton, IN. 765-963-6628. Parts for Ensign are unavailable. Matt helped me convert a MM U propane to an Impco regulator and carburator. Starts and runs good.
 
Like jnf say's they dont make parts for Ensign anymore but the place In Lone Wolf Oklahoma might have some parts, He passed away but she run its now,The last name is like Eberharts Two Way Radio and LP,i dont have the area code for sure, but her number is 846-5633, Lone Wolf Oklahoma,
 
His name was Herman Everhart. I don't know anything recent, but I bought a rebuild kit from his wife a couple years ago and have been very satisfied with it.
 
Sounds to me like maybe you have a problem with
the regulator. Fork lifts use propane. Schwans
trucks use propane. Somebody in your area must
know how to work on them.
 
(quoted from post at 20:05:41 02/24/15) It is Everharts at 580-846-5633

thanks I called her she wants the number of the regulator. and I don't know where it is. I have to go look. She has rebuild kits. I hope its worth it
 

Thanks for all the responses. Like I stated earlier. I'm a new bee at this. But at the bottom of the carb is what I'm assuming is a choke. It needs to be opened all the way for the tractor to start which it does. But you can hear the propane escaping. and if I close the choke the tractor dies so I'm running it wide open. any suggestions. If I close it the propane leak stops but the tractor doesn't run if I close the choke all the way. I'm going to get a regulator rebuild kit. Would it be a good idea to get e carb rebuild kit as well? Or change the entire system to IMPCO? Suggestions are all appreciated..
 
I have a 400 LP we had trouble similar to yours but not the same. The tractor starts with the choke shut all the way, when the tractor fires open choke all the way. you need to be certain that you have a good gasket between head and manifold, part of my problem was a bad manifold which I replaced with a new one. I also fund that my regulator was not working properly because of vaccum leak and hole in diaghram. Replace regulator and cleaned carb. Tractor run great and lots of pulling power. Governor has to be hooked up works like a gas tractor. Hope this helps some.

yes that helps a lot. Thanks a bunch. I'm set straight now... I'll post some pics of reg rebuild.. SOON
 
Closing the choke isn't stopping the propane leak. It is just blocking the leak from your view.

The choke needs to be OPEN for normal running. It blocks off the air intake to the carburetor. Normally the air cleaner is attached to the air intake so that you don't suck the engine full of dirt.

Sounds more and more like I have regulator issues. I will rebuild it and see if that does the trick. Yes the air cleaner is attached to the carb. But with he choke open all the way I can hear the propane escaping pretty bad. Thank you.
 
I suggest you at least price an Impco system before spending money on the Ensign. It will be new and ready to run.

Does it take a new regulator and Carb?? Or just replacing the regulator. I need to find the model # on the ensign regulator and it doesn't have a label of any kind...
 
I suggest replacing both the carburator and regulator, but call Matt at Motec for professional advice.
 
Just replaced the regulator on mine the carb just needed cleaned very simple design to the carbs. My IT manual had a picture of the ensign carb. I have an after market replacement reg. got it from a local propane shop that works on forklifts. Designed to run 60 to 100 hp. can't remember name of it now will look at it in morning and answer back.

Good deal I ordered a carb rebuild kit today for 50 bucks for that model ensign carb that I have. The guy said it was put in 1942. Here are some pics of my regulator I could not find a model # Mrs Everhart needs a model number. I'll probably go with a new regulator. Models are appreciated.

If anyone could give me a model # for this regulator Id appreciate it. So I could get a kit from Everhart. If not a replacement that will work with the installed ensign carb. I tried to call matt. Will try again tomorrow.
 

I called matt at motec. I need to send him my carb only. He's going to machine it. When I take off the carb Im going to rebuild it as I did find a guy that had rebuild kits for the ensign carbs. Then I will send it to Matt. Thanks everybody Ill post some more pics once I've removed the carb. This weekend I rebuilt the magneto and replaced spark plugs and made new cables. Nice little project going.
