Picked up a sears SS/16. This thing is a brute.

The 16hp Onan is HUGE.

These pictures are from the ad:

The yellow "shell" is a wooden block holding the hood off the battery.

My son took one look at it and declared it as his.

A few things to work out:
On idle the engine surges or hunts. Reading, it sounds like an air leak after the carb.
Need to investigate a ticking sound.
There's a mouse nest beside the carb. - see if runs better without it.

Eventually, I want to find a mower and set this up to cut grass.

Nice catch. Good luck with your work.

Nice looking tractor. A bigger Suburban is on my want list. That will make a great mower for you too.

Does that say CF TUG on the sides?

Canadian Forces?

Looks like a military paint job.

[motobreeder]

I'm curious, but CF-TUG was hand-written. I'd expect the CF to include an asset number.
Paint was done using a spray can - there's plenty of over-spray.

Looks like a pretty good tractor.

These old onans are amazing. It's hard to really work one unless you add several hundred pounds to try to get enough traction. I have a 16/6, pulling some logs for firewood this past summer/fall, I'd traction out and the engine never even grunted.

Great find.

I am picking up one the end of February that was advertised here. Hope it looks at least as good as yours.

Nice machine, 1973-74 model. The first two numbers in the engine serial number will give you the year.

[motobreeder]

Just ran out to the garage - the first 6 digits of the engine serial number are: 067366.....

Funny thing. I started the tractor to warm up the oil before changing. As I had posted earlier, on idle the engine was hunting quite a bit.

Changed the oil and removed a large squirrels nest. Now it idles as smooth as silk.?!? Not sure what I did - but I'll take it.

That is a 1973 engine. Tractor was most likely made in 1973 as well. I would spend $18 on a brass float for the carburetor, preventive maintenance. Found here: Onan Engine Caburetor BRASS CARBURETOR FLOAT 146-0380 B | eBay

Called the local Cummins/Onan dealer for a carb kit and float. Good thing I was sitting.

Carb kit: $170.70

Float: $134.50

I see no justification for that kind of pricing. I highly doubt the parts cost 1% of that to make.

I've gotten a few things from him. Great service and decent prices.

Running the SS/16 around the yard and ran out of gas. After re-filling, it wouldn't run - the float was plugged. Pulled the top off the carb and cleaned out the needle and seat.

While I was there, I decided to try adjusting the low-speed jet. It was bottomed out. Twisted it out a couple turns and the hunting at idle problem has gone away completely. Nice to know that problem's solved.

Put in new plugs - Champion H10C. Hopefully that's correct.

Great find! I love the older ones!
