Berny 9 #1 Posted July 15, 2021 (edited) Hello! My grandpa bought me a C-160 at auction it has the Tecumseh OH-160 motor. I'm working on getting it running. I've replaced the spark plug and starter. I removed and cleaned the carburetor and new gaskets in it. I adjusted the carb and governor. I adjusted the valve clearance and ignition pin gap. Compression test says 90psi. It still isn't running very well, it will stutter, almost stall, then pick up and save itself. That repeats every 5 seconds or so. It's also dripping oil out of the breather tube. I think the guy before me may have put too much oil in so I'm going to change it and make sure the proper amount is in it. I'll link some videos that will give a sense of the problem. I managed to score a mower deck for it, and I really want to mow my back field. Any and all advice is much appreciated. Thank you so much! I want so much for my tractor to run properly.

Wheel Horse 3D 3,821 #2 Posted July 15, 2021 Definately overfilled on oil! After that see what it does and move to carbureator adjustment if needed. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,472 #3 Posted July 15, 2021 According to the Lubrication Chart it should hold 2 quarts same as the Kohler. Click on the fuzzy picture to view the charts. 1 Share this post Link to post Share on other sites
Berny 9 #4 Posted July 15, 2021 (edited) Thank you! I'm changing the oil now. Weirdly enough I found a Tecumseh manual that listed the oil capacity at 52oz, just over 1.5 quarts. Maybe I'll start with that and adjust based on the dipstick. Thanks for the help everyone, I'll keep it updated! Edit: I got SAE 30, as indicated by the manual, but it is asking for API "SE" or "SF" oil. Mine is "SP, SN, SN plus, SM, or SL" but after some research it looks like it will work. If anyone has information to the contrary please advise. Edited July 15, 2021 by Berny 1 Share this post Link to post Share on other sites

Discusses oil and it's properties. You really should have an older designation oil such as SJ. What you have is fine for now. Check out that thread and you'll learn a ton of info. Congrats on your C160!! Definitely a bucket list tractor for many folks. That Tecumseh engine makes it an uncommon one. Produced 1974 ONLY and just a few hundred at most. I have one here for a future restoration project. 1 Share this post Link to post Share on other sites
Berny 9 #6 Posted July 16, 2021 Thank you! I think I just saw some toro SJ oil at the hardware store. Dang, I should have got it. I'll check out that thread. I will get it running and use it for a couple months then maybe change it again and put SJ in it. 1 Share this post Link to post Share on other sites

You can get it at Walmart for $16 a gallon. SJ is an older formulation that does in fact have more Zinc than the newer SN but I guarantee that Toro oil will be more than $4 a quart!

Rfp55 33 #10 Posted August 20, 2021 That Tec OH160 has internal counterbalance shafts and weights (like dummy crankshafts) - that someone may have mis- lined up post rebuild. They're not real obvious or intuitive to get right. Will give fits if out of whack. Good heavy built engine worth work imo. And free online service manuals are a good idea. Is the reed valve in breather backwards causing cranckcase pressure? I have found lots of unusual stuff from previous fixers. 2 Share this post Link to post Share on other sites

There's pin holes that must be on the bottom as installed on the engine so the oil will drain. 1 Share this post Link to post Share on other sites
