I am getting ready to work on the Case 446 this morning and the first thing I saw was that the square fender was a perfect perch for my coffee mug.

Yesterday I washed the tractor, changed the engine oil, charged the battery, cleaned the spark plugs, replaced some bad/incorrect wiring (It seems that every old garden tractor I get has hacked wiring). I also drained the fuel lines and cleaned the dirt encrusted outer side of the carburetor. Now it turns over. I think that I need to take a look at the ignition system next and verify spark to the plugs. I think there are points on this Onan engine. I learned something, be careful when you remove the air cleaner housing from the carburetor. The mounting screws can fall into the carburetor and into the intake manifold. Fortunately, I was able to fish the screw out with long pair of needle nose pliers. :madhop:

Sounds like fun, my brother has a Case with the hydraulic tiller and it looks like one heck of a tractor. I know what you mean abut little screws falling, seems like every time I do something my old fingers will drop something and it always winds up somewhere like in the carburetor if working there or in some hard to get to place. Glad I have a magnet on a stick and long needle nose pliers. Good luck on starting the ole babe up.

Thank you Tinner, I think she will run, just needs some care. I am no real mechanic, so I learn as I go. Definite fun!

Ok, I verified there is no spark on the plug. The points and ignition seem a bit corroded. I will replace the points and condenser, but will try to work with the old ones first.

Just about the worst set of contacts I've seen! That carb is a Marvel Shreiber DD model. They can be a bit testy, but first get the spark. Maybe you'll get lucky on the carb & she'll run right away.

Cleaned up the points and she runs. The engine speed tends to wander a bit, but not bad for first run.

Glad to hear you got it running, sounds pretty good.
As for the "Wandering" you hear brand new engines do that much sometimes :D
Might want to run a little seafoam thru it... can't hurt.

Didn't take ya long to get her running. The Onan in my Massey 1655 likes to wonder at idle sometimes. I have tried adjusting the carb and rebuilt it and it still does it, so I just wrote it off as nature of the beast.

I think the whining is the hydraulic pump. I think this is the way it is supposed to sound.

Square fender Case tractors are great for setting a lot of things on, not only just the fenders... just take a look at my Case 222 sometime, if you can find it under all the stuff I set on it LOL.

Mark, sounds great. I'd try the seafoam before doing a lot of tuning. That seems to help sometimes. I love those Onans.

No need about scratching the paint on this one. I spent some time today buffing with rubbing compound. Makes the paint shiny, but also you can see the rust spots and scratches more.

I have heard about Seafoam but have never used it. I did put a small amount of Marvel Mystery oil in the gas and oil. How do you treat the engine with Seafoam?
