Congratulations on your new Case. Nothing against the Sears products you were looking at, but I think you picked the winner there. I hope you got a good deal.

That is our new barn! Honestly, the barn almost sold the house. More pics to come. Thanks for the heads up on Brian.


There is no absolutely no limit on old barn/shed photos. Really. 20 is good round number, imo.

Very glad you got the tractor that should suit your needs best.
I wish i could be of some assistance on the carb issue, but what I know about ONANS would just about fill your average thimble.

Oh, and I will second the above post about using carb cleaner to look for leaks.

The hunting issue could also be the governor spring is in the wrong hole/misadjusted. Here is a link to the Service manual on this engine.

That's a good thought about the governor spring Ken . ^^^ That link to the manual should help the OP out a lot too. Thanks!

I have not addressed the the governor spring yet, because I want to print out the service manual first (Thanks for that, Ken!). We still don't have Internet in the new house. :-(

So I had the tractor out running it around the property today. What I'm finding is that a little ways into a session of continuous driving, it begins to lose power. Give it a litte choke, and it pops right back to full power. Sound familiar?

Oh! And here's an exterior barn shot:

I'd love to have that barn. That is cool!
Sounds like it's running lean after a bit.

What's a good price for a three-point hitch?

Under $250 is a good deal.

Not good but Great! :D

A few things Case,
1)both Case 3 point and sleeve hitch plans can be found on-line.
2)As far as the carb, also check the O-rings on the two needle valves,
I had one Onan that was driving me crazy until I found one was split, causing x-tra air to enter.
3) Many Onan parts can be found at Searspartsdirect.com,link is below,or you need a part # to in-put into part# search.
4) Part and owner's manual per your tractor serial # should be the first thing on your list to get, both can be found
as a rule on-line for free.
5) Good Luck with your tractor, http://www.searspart...Model=B48M&blt=

Onans will hunt when running lean. The carb may just need a good soaking in a carb cleaner can, you can get that at the local auto parts store, Gumout among others offers them, then using a spray can of carb cleaner, blast out all the different tubes and orifaces, anywhere gas or air goes. Most likely there is dirt or varnish in the jets causing her to run lean, which will also cause it to run HOT, a big NO NO on an Onan. I have to put a new carb on a 318 JD as we cannot get the jets cleared, new carbs are $252! The intake runner that goes to each cylinder is made of 2 seperate castings and the gasget has a tendency to go bad and leak, the carb cleaner/wd40 test they describe above is the way to test for that. I have rarely seen the block to intake runner gasget go bad, but the runner one I have seen many. Most likely its the carb though. Do not work her hard till you get that problem fixed. Great buy, enjoy her. Mike

Hello! Nice looking black frame 448 you have there! Gary's place (www.gphope.com) is where I get parts for onan motors. He is very reasonable. his phone number is on the web site. Give him a call about your carb issue (yes, he or his wife will answer the phone) and he will help to straighten it out. A very knowledgable person. Knows his onans very well. His shop rebuilt the motor in my old case 446 for me. Did an awesome job.

3-point hitches are expensive. expect to pay at least $600-800 for one. A sleeve hitch will work too. They run in the neighborhood of $200-400 bucks.
