Remember the tractor that I recently put together from 2 tractors ?
The front half is a AC 710 3 speed frame,the rear half from the bevel box back is from a 912 hydro.
The hydro linkage,brake linkage and gas tank are from the 912 also.
The engine is a very nice cast iron 32 c.i. big block Briggs single that is a later gear drive starter engine with internal alternator.
When I pulled the engine off the shelf it did have some issues.
I had,had it setting around for close to a year but had never ran it.
It didn't want to run so I started tearing into it.
New valves but they had not been adjusted so I pulled them out and filed the stems until they were in spec.
The flywheel key was sheared so I replaced it. The mag was touching the flywheel contact so I adjusted it.
I pulled a carb apart and cleaned it up good and put the engine back in ( yes like a dummy I put it in to find i had to take it back out ).
Once the tractor was all together and the engine in,it seems to run and drive very strong.
So the hydro got fresh fluid and the biggest of the three filters that you can get for this setup.
The engine got fresh oil,air filter,and fuel filter.
The steering and chassis is all greased up.
I gave the tractor a couple of jobs moving other non running tractors around the property and it seems good to go.
So this evening I drug out a very nice 48 inch deck and slid under it for the last mow or two of the season.
The tractor,engine and,deck are all very strong and were doing a fine job...until...
The left side blade found four feet of wire. The wire wrapped up tight on the spindle and locked the blade up breaking the old deck belt.
I'm happy with this build. It's a good strong tractor and the torque of a big cast iron Briggs even at lower RPM is enough to make you smile.
My controls are a little different than stock.
Theres a push button where the ignition switch used to be and a toggle switch shuts the engine off.
The rectifier wire runs up to the amp gauge and back to the hot side of the solenoid.
These are very stout simple machines and I like simple dependable,easy to work on wiring too.
What started this build was a fairly badly mangled 3 speed transaxle in the 710 and the front frame and steering had been mangled badly on the 912 hydro.
Anyway theres a entertaining short story for you with a happy ending.

I like a good story with the old iron. That's what you call one piece at a time build. I have a 16hp cast iron b&s in my Mtd990. I love to hear that thump. My bil was bragging about his 24 hp new tractor being bigger, yeah right. I told him he would have to have two of them to out pull this & only if your frame dont wrap you up first. Glad you got it up & running.
 
I agree. It does suck to have to pull the valves to file and adjust them,set them back,check,file some more,etc. And if you you go too far you just ruined a valve.
Seems that they would have went a better route.
I'm not crazy about the Flo Jet carb design either although I'm pretty good with them after 2 and half decades of working with them.
But when these big old cast iron Briggs are running right I love to run then and hear them run.
