Can you believe it ran like a champ with a carb I rebuilt from a 7hp tecumseh.(stole it form my snowblower LOL) Now I need to find the right carb,so far in searching there seems to be no replacement for the original one.So if anyone has a junk on I can rebuild let me know. thanks.

The only difference the proper carb, (larger) is going to do is give you more airflow, power.
If the one that's on it runs good leave it there until you find a good proper size one for it.

Congratulations, I'm glad it runs so well, it's just a rush to have something old like that running again

I know it! It is like being a kid at Christmas LOL. Now I need to buy a seat tomorrow, That hurts driving around sitting on a flat piece of steel.

Congrats on the runner! Couldn't believe you had it going already.

As for the carb, check with BHTS, he has a few older Sears units with teccy's in them. The big difference may be the linkage hookup, but you're creative. Ask Bob, he'll probably know what will work and what won't. I also have seen some Kohler carbs adapted to some of the tec units, you may be able to go that route also.

That's great news Chris. You're off to a fast start on this project!

Thanks for the info! And it's funny you mention the Kohler carb, I always liked the Carter carbs and was already thinking about making an adapter plate.

I notice in the service manual a "free wheeling valve" on the hydro. It says to adjust to drive position. What is the "drive position"? And do I have to turn this to relieve pressure so I can push the tractor? I can't seem to locate a operators manual for a MF12H, and I could swear I saw this discussed on a thread one time.Thanks in advance!

[MH81]

It's on the front of the tranny down low and looks like a small "T" handle. One end is longer to designate position. I think long end down is engage and long end up is free wheel. If you've been driving it, free wheel is the opposite of where it is now ( )

Don't expect to set any land speed records with it in free wheel, I remember there still being some drag, but at least you aren't (shouldn't be) damaging anything.

[HowardsMF155]

On my Hydro, the free wheel valve is located on the front of the transmission, up near where the frame is, and is on the left side. As I recall, long side down for freewheel, long side up for drive.

Went out and checked....Mine is as I described above.

Thanks for the info! I had found it but had no clue what position it was supposed to be in.I just seemed hard to push, so I stopped and checked here before I damaged something. Also I went and started disassembling it this afternoon, No turning back now LOL. The steering wheel is shot and rusted to the shaft,I tried everything and it wouldn't budge. So I cut it off with a die grinder. Soooo if anyone has a good steering wheel, I'll buy it from you.
