OK guys, I got the rebuilt carb back from Jestin at Tube Frame Restorations yesterday. Put it on a, squirt of starter fluid, and we are up and running. It ran strong and I finally got to engage the hydro for the first time. I was able to use the lift cylinder, It would push great but needs a lot of help to draw back in. But I have other issues right now.

This morning, hoping to actually drive it under its own power, I go out and no start. It backfires through the carb. Has spark and fuel. I believe there is no timing adjustment on the tra12d. So what could be the problem?

Here's 2 pages that cover the timing procedure on the solid state ignition: Wisconsin Solid State ignition service/repair info - Manuals - Garden Tractor Talk - Forums

Thanks Doc, I do not have the external module. It was running great yesterday and currently has good spark. It backfires through the carb, what are some causes?

The only thing I can think of right now is check your valve clearances and make sure they are working properly.
Other than that the only other thing it could be is the carburetor...

So i checked the valves for operation, everything was operating properly. I squirted some wd40 in while the valves were open, hoping the help anything that might be sticking.

Closed it all up, opened the fuel valve, gave it a crank and no backfire. Cranked it again and it started up.
I let it run for a bit then I shut it off and let it sit for 10 minutes. Tried to start it at what do you know it started.

So now for the test that I have been waiting for. I put a board across the fender supports for a seat, engaged the hydro unit and gave it a little forward then a little revese. All seemed well so out of the garage and into the yard. What a great ride.

The best I can tell this unit has been sitting for 10 years and with just a little patience, tlc and help from you guys it is alive again.

I finally made a little time for the 1256. Installed the battery( seems to me the factory battery mounts are worthless), sanded and primed the tins again. I have been starting the tractor every day and running through the hydro. The lift cylinder pushes good but it pulls very slow. How do I know if the lift cylinder or the control valve is the issue?

Can anyone give me a model number on the mower deck?

The lift cylinder will have more power when extending, than when retracting, since the area of the piston is greater on the "push" end of the ram. ......For a given volume of flow, the cylinder should retract faster than it extends, since it has a smaller volume to fill. ....Does it still retract slowly if it is not lifting an attachment? ......Check your linkage to the control valve to see if the valve moves to its extremes in both positions.

If your mower is a 42" cut, it may be a model 18457, since it is green. .......The 42" mower usually sold with the 1256 was #18422, (I'm almost certain it was painted red) and listed for $187.00 in 1970.

The last year for the green decks was 69' . But who knows, the Green deck may have been remaining stock when sold with that 1256.
The mower is definitely a 42''

Thanks for the help. I am pretty sure this deck was not the one that came with this mower. The guy that had it also had a 1050 sitting there and he had no idea. I needed a deck and it was part of the deal. I hope it will mount up to my 1256 without much touble. Before I work on the deck I will have to make sure it does fit.

Its been a while but I have done a few things the the 1256. Since my last post I redid the mower deck got it mounted and tested, the 12 horse really turns the deck strong.

Here are some pics of what i've been up to.
