1160 comes home

Went over today with a charged battery and got the combine started. Runs a lot smoother and crisper than it did, but still needs full choke to run at full RPMs. The only thing left it can be is a bad carb. I've changed all the ignition parts at least twice, some 3 times. Replaced the whole fuel system and made sure it works, made sure the gas level is good in the carb. Today I gave it the either test, sprayed the whole top of the engine and found no leaks. I've looked at and cleaned the carb several times and had it done by someone claiming to be a pro. Still needs full choke to run at full speed. Guess I'll have to pull the carb and check it again, maybe get larger jets or drill them out a bit.

Anyway, it's home now and will be in the shed and easy to work on now.

Here is a video of it running, this is with full choke. Will idle with no choke, but won't rev at all.
Combine running
 
I know squat about mechanics but for what its worth, I purchased a 630 gas on an auction once that idled just as sweet as can be at the auction. But as soon as you throttle it up much it would cough and sputter, would only run on full choke. Barely got it loaded on the trailer to get it home. Long story short, turns out it had been sitting so long that the governor weights were froze up and wouldn't advance. Of course your 318 is nothing similar but thought I'd mention it. Strange things sometimes.
 
What carburetor? I was thinking Carter "BBD", but the little I can see in the photo doesn't look like one???

Some sort of Holley?

Does it have a "power valve"?

An accelerator pump?
 

I had a tractor that would not run at above idle unless choke and would not travel down the road without full choke. Played with it for a while then tried adjusting the idle screw. I found a spot where it idle nice and did not require choke. Just my 2 cents.
 
if that is the original carb from that engine its not the jets, as they worked fine.. it also has an accelerator pump same as the vehicles. accelerator pump not working only cases a hesitation.from this video hard to tell whats going on. as i asked before, was the carb dissasembled and soaked in actual carb cleaning "gunk".appears like a passage is plugged.may people spray stuff from the can down carb when running and call it cleaned,... but that is useless! what happens when you open the choke at full rpm?? also to me it sure dont seam to be reving up enough.?? should be idling about 700 rpm, anh high idle around 2000 rpm would think... dont have actual spec.
 
If that is an old Carter, or even if it isn't, check that isn't warped where the top & main body meet. They often warp and leak air into the mixing chamber for the main circuit causing a dead-lean condition like you describe. Been a long time, but IIRC you can take off enough stuff to flat-sand the body but you must do the top with a hand file because of the float mounting arms. Also make sure the control rod moves up and down freely, the throttle should pull it down into the main jet at idle and allow a spring to raise it as the throttle butterfly opens, then the vacuum diaphragm should pull it back down again as manifold vacuum builds.
 
Case powered by Mopar, it just doesn't get any better. I think you'll really like that machine when you get it running right. Don
 
So it has dual exhaust, never seen that before. Imagine this each 318 industrial cost the Case Company, 100 bucks!
 
All the Chrysler v-8 engines on Case combines use dual exhaust pipes into one muffler. I have used a "Y" adapter and put a 830 muffler with a turnout on a couple 1660s here. Cheaper than than the original muffler....if it can be found.
 
When I got it one went out as is, the one with the flipper was turned up on the side of the motor. I just moved it out by the other. They are not in good shape, but when I get the motor running good I'll fix them up so they don't leak and are looking better.
 
Jon,Very happy to see you got the 1160 home.Before pulling carb again rule out the weights sticking in the dist.I had that happen years ago on a 1160 and acted the same way.Double check all the easy things.What's the numbers on the carb?
