Default 15HP Pattin Bros running!

Hey all,

after about a year, my Pattin is running! We belted it up to a tractor and ran it for about 2 hours with no compression to wear in the new rings and bearings, then (optimistically) tried hand starting it... then quickly went back to the tractor! hopefully i'll find the happy spot soon and be able to bump start the engine by hand.

Well done, Connor.
The engine appears to be loosening up quite a bit. You'll soon find the right combination. It's those 95 degree days that the trampin' quickly does a person in.
Thank you for sharing.

Thanks for sharing Connor. The Oil Field Engine board has been a little slow lately, nice to see some activity on here.

Is your gas cock a true diamond valve. The intake cake is also the governor for the engine .

yes, it is a diamond valve but was missing the handle, thus the non-pointer handle.

I did read up that the intake valve was the governor... but i don't know how i feel about that. with the both valve loose and tight, it oversped itself. in the end of the video the intake spring was tight, valve at 1/8, and globe valve on intake choked down a decent amount.

I can't quite figure what intake valve spring tension correlates to low speed and high speed. I understand the mechanism behind it, but based on my limited experience with the engine i don't know what setting is supposed to be what. can anyone shed some light on it? this weekend i'll be running it at our summer Zagray farm show, so i'll have plenty of time to play with it.

Connor, do yourself a favor and put a pointer on the valve handle. Even a temporary pointer will do. Without a pointer, you have no way of consistently opening the valve to the same place every time you start the engine. The setting will change slightly with changes in the weather, but it'll get you close enough. Whoever the person is that's operating the engine in the video obviously realizes the importance of being able to make fine adjustments on the gas valve. I keep a screw driver at hand and use the handle to very lightly tap the gas cock handle to adjust it. A few thousandths of movement makes a big difference especially when the air is restricted.
On the 15hp Pattin Bros. engine around here, the inlet valve spring has a modest amount of tension on it, essentially enough to close it reliably. The speed is regulated with the gas cock. You can restrict the air a bit to fine tune the engine, but don't close it off too much. The engine needs a decent size charge to make the transfer. Propane has a wide enough flammable range that you can go from full power down to too little gas to even roll the engine and still have reliable ignition without changing the air. Also keep in mind that when you restrict the air, you put more draw on the fuel. As a result, you'll need to close the gas cock more making the adjustment even more critical. I would recommend that you not close off the air any more than half way if at all until you get the hang of it.
Have a great time!

Kirk

https://youtu.be/d7eT-vyz6fEConnrad I had 1 just like it, mine did not like much fuel to start, but needed more to run, air was cut down to about 1/4 open, int valve had just enuf tension to close it ( very criticle) i would adj gas valve so it would fire on roll over then add fuel to keep it running, mine did not act like the gov would catch the engine on overspeed, but my first one of that type, and i wont let one run very fast to check it anyway, mine was ser # 51, tom g has it now, he prob knows more about tuning, good engines

Another recommendation I have is to shorten up the air inlet as much as possible. The valve that you have will suffice but get rid of the nipple and ell. If you don't like the aesthetics of the valve, a nipple with a simple slide on the end works well.

I find it interesting that kirk and david's suggestions for basic adjustments are nearly opposite! I think it demonstrates how each engine is a little different.

The gas valve handle has a square end that makes a decent pointer. eventually i'll swap it but it's pretty easy to see where it's pointing. And that was me in the video! I was having a hard time fine-tuning the gas valve with the engine rocking back and forth 6 inches or so.

I'll have plenty of time this weekend to monkey with it during our show. I will probably try to start it with the settings from the first run, and go from there. I made some wheel chocks too! I'll probably make another video of it, and report back on how it likes running.

Connor,
Yes, each engine has its peculiar nature......and starting procedures are like chili recipes, everyone has their own.
The Pattin Bros. here, with no load, runs best with the air 1/4 - 1/3 open. Yours probably will be similar. Being a relative newbie, you might find it easier to manage with the air not overly restricted, especially without a pointer on the gas cock. Once you find the sweet spot, you'll likely find that a movement of 1/32 of inch at the end of the pointer will be the difference between running away and not running at all.
The inlet valves rarely shut the gas off completely. To test it, open the gas cock and try to light it at the air inlet. With an extended air inlet assembly, the leaked gas will fill the pipe and give a rich mixture while you're tramping it. Once the engine fires, each successive intake will be lean. You can use that to your advantage, but it can also cause a lot of grief.

Kirk

Ran the engine for probably a total of about 12 hours this past weekend! Saturday we had to belt start it, but on sunday i spent about 1/2 hour kicking the flywheels by myself with a helper on the gas valve and eventually got it started! it likes a loose valve spring, air 1/3 open, and gas at 1/4 to start and 1/8 to run. It ran very evenly, 4-stroking most of the time. I had a orange heat tube to start, and after i started it, i backed the hot tube flame off just a little.

Lots of spectators were interested and loved it, and lots of questions of what it was used for, since in CT we don't have much in the ground except for rocks! The guy i bought the engine from also came down and was very happy to see it run.

Just got my first big engine, it's a 15 hp Patton Bros. I'm hoping that you can give me some info about it. Maybe a manual so I can see what I'm missing, and maybe where I can get some parts.
