782 getting hot

[ol'George]

ok
Do you have the adjustable main jet on top of the carb by the throttle shaft?
or it is the one on the side by the bowl lip?

The ones on the side by the bowl are lean from factory, and if slightly cruddy inside, they will hunt/surge and run chitty but just need cleaned and adjusted.
If the main jet adjuster in on top, just tweak it as they are fully adjustable.
( but can be cruddy inside also)
I just happen to like those old 2 cyl opposed twins, verses the new fool injected
"v" banks.
Nuttin wrong with new, I just like old skool and they work, and sound sweet to my ears.
Luck!

I'll have to look. I didn't get a chance to mow last night, nor did I mess with it.
It was sitting at my father in laws house this winter and it wasn't starting right. So I just had my father in law drop it off at the case IH dealer for a carb rebuild.
They rebuilt the carb, changed oil, new battery, air filter, and put a electric fuel shut off solenoid on it.
Then I picked it up for snowblower duty and we never got any more snow. Then it sat until June 1st, when I decided to pick it up and start using it.

So I highly doubt that the carb is dirty. (And I don't want to hear anything about the dealership.) Given the dealerships relationship with my family.
It might be possible that they set the adjustment screw to a factory setting causing it to run lean.

Ha-ha I remember then I was with my grandpa the first time when he heard a 25 horse v twin run, he said that old thing is on its last leg and going to blow up..... Haha it was brand new....

My hot-stalling 122 actually kept running when I firewalled the throttle. Good to know-- thank you.

I wish I could say that; I'm massively upside down on this 122, and I got it for free.

I didn't say it wasn't worth fixing,.... I'm just saying that I personally wouldn't put a $2100 motor in it. But, I digress. Money doesn't seem to be an area you lack in. If I had more of it, I'm sure i would spend it differently.

On this subject, what would you do if you had a 782 and the KT blew up?

I've got 2 7's, one with an S1 and one with an S2. I really enjoy running them, they are in good shape, and both are workers.

I'd want to do a Command swap with a new engine, but is it really feasible? I've not seen any used commands (or engine donors) locally.

Seems like the majority of 6-782s go to the graveyard when they die but I'd sure like to keep using mine for a while. Tough spot to be in.

I don't know Brian. I pick on people all the time on here for attempting to fix an H twin because, in my opinion, to fix it right is just too costly. By the time you're done you can almost buy a new CH. I'm in the same boat as I have a pretty nice 682 and a very nice 582 both with bad engines. I have a used CH I had planned on sticking in at least one of them.... but have yet to do it. I am with Ol George in that I really do like the old H motors. More torque than a V. I can't really give you any sway one way or the other than to say that it's awful easy to put a CH in a 782, and that used ones are pretty easy to find. (Or a Vanguard.) Me.... I could go either way. Fix the old, or install a used, or even new, CH. One way or the other it's just time and money. I do know one thing for sure..... none of mine are going to the boneyard over a bad engine!

I am of the opinion that replacing the engine in a 782-2072 that has a blown engine is a way better move than spending money on a new plastic POS that is available today. I agree with Jon that they are probably not worth it as no body will give what they are worth when rebuilt but they are better than any thing you can buy today for the money you will have invested.

I just finished rebuilding a 1872 that includes a warranty take out 28 hp command EFI that I found for $1,100, I rebuilt the rear end and hydro, added a three spool hyd valve, front and rear hyd outlets, a three point hitch, New AG tires and a paint job. With the initial cost of the tractor I have around $3,500.00 invested in it and it is the nicest running and driving Cub Cadet I have ever drove. This tractor should last another 30 years if taken care of. What can you buy today for the same money that will last as long, and it is way better looking the stuff that you can buy today.

If it was me I would try to see why the 782 is overheating and correct it. Most likely adjusting the carb will cure it. I always run the hi speed fuel mix a little on the rich side to help with running hot. If and when you decide to upgrade to a CH engine having a good running opposed twin to sell would be a plus. Someone may have a use for it. Good luck

Mowed twice with no adjusting of the carb, at wot.
No issues.
I turned up the main 1/8th turn and the idle 1/16.
Mowed twice since turning them up. Still no issues. wot

Side panels still off.
Going to put them on and see what happens in few days when the low parts of my yard dry out and I can mow there.
