Hi David, your carburetor is leaking internally. This means your float needle is not closing properly! If you have some fuel coming out of the breather, you might have oil+fuel now mixed. This will mean you‘ll have to do an oil change. I hope this helps. Regards Andreas
Sometimes the float needles have rubber tips and they dry out over time. Once replaced, they work like new with the correct float adjustment. I‘m not sure Kohler ever made carbs with rubber orings at the bottom of the float seat, but there are some of them out there on different makes. The needle is then usually made completely of steel. Regards Andreas
I rebuilt this engine, because the tractor it came out of was sitting in a field for many years. To ensure everything is within spec. I take an engine apart, measure everything and replace whatever needs to be replaced. So far I haven't had any issues with my JD 300 and it's cuts grass like a champ! I can cut two feet tall grass and it doesn't bog down...talk about power. Thanks for your comment, Dan. Regards Andreas
@@WorkshopRebuild I get it. I just don't have that kind of time to spend. I did put new valves and recut and lapped the seats in mine (K341S) due to a bad leakdown test and some misfiring. The valve seat damage was obvious, too. Surprisingly, the cylinder looked good. Anyway, I have 5 tractors, all older models, and the WH with the Kohler is the smallest. There's always something to work on so I usually don't mess with them until they get bad. But yes, those old Kohlers are something else.
A year late on the guessing game, but a 216 would be my first wager, or a wheel horse. Thankfully they made a billion of these in a lot of GTs so I can still buy parts 40+ years later!
Thanks for your comment! You were very close, but this engine was eventually placed within a John Deere 300 garden tractor. You're right, they made tons of these engines back in the day and that's another reason why so many are still around up until this day. Another give away on these engines are the last couple of letters. K341 is for the engine displacement and the amount of cylinders. "AQS" were the factory options for John Deere. There were different oil-pans and dipstick tubes and that's what AQS basically meant during the assembly process. Thanks again for tuning in and sharing your thoughts! Regards Andreas
Hi John, if you know your engine is running well, I would check the engine mounting bolts and the engine mounts. These bolts do have lock nuts on them, but it's possible that they have come lose. If that's tight, check to see the condition of the rubber engine mounts and the rivets that are on the frame. These engines are notorious for shaking quite a bit, but with old or loose engine mounts, it can shake even more. I hope this helps!
Great guess! It sure is from a JD 300! I did my research afterwards and saw the K341 engines with the counterbalance gears! I'm lucky I didn't stumble upon one of those!! :D Best regards
That‘s a very good guess and it wouldn‘t be wrong, because the JD316 had a 16HP Kohler engine. This came out of a JD300 garden tractor! The JD300 later turned into the JD316, which was mechanically identical, but they updated the panels a little bit. Thanks for your comment, I appreciate it!
How did you manage to turn it over with that much rust in the bore? Lol. I thought it was an International or JD at first, but the wide bottom block and bits of orange/red paint makes me think Jacobson or Wheelhorse. Noticed a little water in the oil pan. Definitely burning oil. Piston shows a little wear and minor scoring too. Hone it, throw in a piston & rings and send it out the door lol
I turned it over about 30 degrees with a socket and breaker bar. It was mainly to check if the engine is free. This engine is out of a John Deere for a fact, so you weren't far off! Great guess :D Yes there was water in the oil pan indeed. Very little, so I'm not too concerned about it. The piston does show wear on the bottom end and once everything is clean I can take proper measurements. I am leaning towards a full rebuild kit (piston, Con-rod, and full gasket kit). But I'll see very soon here. A light hone with take any glaze away on the cylinder wall. Stay tuned for the assembly video :) Cheers!
Yes, this Kohler K341AQS was rebuilt and you can find the videos in my John Deere 300 Playlist! I hope this helps, Regards Andreas Link to the playlist: th-cam.com/play/PLJYgf55IHeu-g89fJNQ6winaScBsZNhaT.html
That's a good guess and it would probably fit right in there without many issues. Nevertheless, this engine eventually got dropped back into the John Deere 300 garden tractor it came out of. Cheers
@@jdrobertson2203 They had different versions of the K341, some had balancing gears and some didn‘t. Maybe you‘ll even find some differences on your engine block, as each company (JD, Wheelhorse, Cub Cadet...) instructed Kohler to design the engine to fit their garden tractors. I hope this video will assist you along your engine rebuild. Thank you for your feedback, it‘s much appreciated!! Regards Andreas
@@hunter7476 The brand is correct and according to the engine, a 216 would be a great answer! I will be posting a video soon on my new project...so stay tuned :)
Great guess and you could be right, but this engine ended up in a John Deere 300 garden tractor. Many Kohler engine with QS at the end were John Deere specific, as they had some different features from the factory. Best regards
That is a correct guess and at the same time, I learnt something! I don't have much knowledge of wheel horse garden tractors, but maybe in the future I will stumble upon a project:) This Kohler K341 was placed in my JD300 garden tractor and it runs really nice. Cheers
Either a JD 300 or a 316 I believe
That was a very close call! It is a John Deere 300 indeed! Best regards
Can anyone tell me why I've got gas coming out of the crankcase vent on my 14 horse kohler? Cub Cadet 149.

@@WorkshopRebuild it's been sitting with no gas in it for several months. Sounds like it got dry on the inside of the carb. Thanks again.

I cannot think of one single reason to tear down one of these motors unless it was run dry. They don't just stop.

i have the same engine my john deere 300 series what would make the engine shake alot when it's running

John Deere 300 or John Deere 316 (1978 model only) Be happy it wasnt one of the k341's with the counterbalance gears in it. (AKA grenade gears)
Great guess! It sure is from a JD 300! I did my research afterwards and saw the K341 engines with the counterbalance gears! I'm lucky I didn't stumble upon one of those!! :D Best regards

@@jonmyers8046 Yes, you were much closer! I will have an update on the engine rebuild very soon. Stay tuned :D
John Deere 316
Very good answer. It was the same engine like in the 316, but this one particularly came out of a JD300 from 1975!
Made any progress since last year?
Yes, this Kohler K341AQS was rebuilt and you can find the videos in my John Deere 300 Playlist! I hope this helps, Regards Andreas

@@WorkshopRebuild That's great, thanks. 😁👍
Good thing you took it apart that cylinder wall didn’t look too healthy
Yes you're right! That's exactly why I always disassemble a tractor/engine that has been sitting for many years! Cheers
Bobcat 310
That's a good guess and it would probably fit right in there without many issues. Nevertheless, this engine eventually got dropped back into the John Deere 300 garden tractor it came out of. Cheers
Wheelhorse D160
Great guess and it sure would fit in a Wheelhorse D160! This engine was removed from a JD 300 garden tractor. Regards Andreas
@@WorkshopRebuild lol that’s why I was watching the video. I have a D160 and I need to rebuild my k341s. Great video!

My guess is it came off of an old wheel horse
Close, but not quite right! Maybe the colors of the Thumbnail hint towards a certain tractor :D
@@WorkshopRebuild hmm I’m thinking it could be out of a John deer 216?

Ariens gt16
Great answer! The Ariens GT16 had the exact same engine. Kohler produced 4 different versions back in the day. Best regards
1650 massey ferguson or snapper
