New 982
 

Hi everyone. I'm a IH Cub newby, and my recon on this site helped me quite a bit already. I just picked up a 982 (with Matt's encouragement):beerchug: and the engine doesn't run too well. It was sitting at a tractor dealership for a week during some heavy rains with a broken gas gauge window, and it therefore had water in the gas. I used drygas and Seafoam, and it ran well enough (no smoke, but rough) in that I was confident to purchase it, especially at the negotiated price and the Haban 60" deck.

I noticed that the plugs in it were RV15YC, one step hotter than the spec RC14YC. That's not a good sign. I am going to throw the 14s in tonight. I peeked in the head thru the plug hole, and there is moderate carbon buildup. I filled her up with non-ethanol premium, a good dose of Seafoam and MMO. I filed the points, ordered points and condensor, set the gap at 0.20 (they were at ~0.16).

Now, I have problems similar to young enthusiest in that I get a gas fountain when trying to throttle up, and it catches, but doesn't sound like it over-revs. It'll run for a while, then start to cut out and I choke it and throttle down to keep it running. The governor is tight and appears to be working as designed.

Yesterday I mowed with it, and it kept running at half choke, but stalled a few times. It blew smoke at startup (no waiting was needed). Today it's running fine with no choke, and there's no smoke. The Seafoam may be workin to blow some crap out, hence the smoke. It runs now, but still misses a bit (as it did yesterday under choke). I also noticed it will rev when I slowly choke it, then it'll sputter. I think that's a clue :bigthink:

I've narrowed it down to: The coil, the wires, carbon buildup, points and condensor, carb settings and sucking air, and maybe, maybe fuel pump vacuum line blockage. Or all of the above.....

I'm going to change the breather element and adjust the carb needle and jet. Is it a Walbro? How did they hide the name on it? I'll try to find some service manuals, but in the meantime, could someone help me out with the carb settings? Does anyone know the resistance for the coil, cold and hot?

The fun begins. The 982 is my "new" daily mower. Thanks a lot!

No one ever states what they paid.

No not a Walbro. Nikki

Check for vacume leak at intake gasket, I've heard of that as a problem.

I went hotter with the plugs in my Kohlers and Onan, no problems.

Pics?????????????????????????? red or y/w?????? options??????????

I didn't think it was proper to state what I paid, so I didn't. $1K at a dealership, and they threw in a hydraulic cylinder rebuild kit because it has severe internal leakdown. Owned by one of the dealership's mechanic, and absolutely no engine oil leaks. No dings, normal paintless spots & scratches for its age, two seat cracks, but that nice deck. No 3 pt or pto. 392 hours. Oh yeah, bad gas tank cap. I know...everybody loves a picture. Here you are!

Thanks for the tip. I cleaned the carb, and probably will rebuild it, and replace the intake gaskets while I'm there. I tested the compression. Exactly 80 for each cylinder. I am unfamiliar with Onans, but that seems low.

I just replace the plugs. Yesterday, they had evidence of fouling. When I pulled them now, they were clean as a whistle. Love that Seafoam! I put NGK equivalents to the 14s in it. I backed the governor stop screw out, just to see if that changed anything. Then I warmed it up and mowed with it, and it wouldn'tt run unless fully choked. Could be the governor.

Well that's a good deal. Yeah 80 is low. Might do well to clean the carbon and valve seats and with new head gaskets....


Scott

This can't be right.....

No the wheels are not correct.

Scott

What about the wear against the mower lift bracket by the outboard lift arm? Is there supposed to be a bracket to connect the two?

Nice 982 deputyrpa! Thanks for sharing your pics. :beerchug:

Nice 982 super. Now a question regarding the seafoam, do you put the seafoam in the carb just like you would on a car or in the gas tank?

That's for front attachments and has noting to do with the deck.
The reason it's below the floorboard is it would otherwise be in the way of the brake steer pedals that your's doesn't have.

Note the pair of pedals on the right side.

Thanks everyone.

Nice rig Scott!

I realized that this 982 did not have the turning brakes, but there is a well aligned hole in the mower lift bracket which looked like a connection point. The rubbing bothers me, so I'll try to see how I can clear it.

As far as the Seafoam papaglide, I only put it in the gas. About 4 ounces/gallon. I did not want to draw it in directly into the carb because it wasn't running well enough. I was afraid to hydrolock the engine. I will try it before I pop the heads off.

I also found compression specs for the Onan P218 engine which indicates the acceptable range of 75-115psi. I wonder if its the same for the P220. I also found the 982 Owner's Manual link on this site, which contains the carb and governor settings. I have to get a hand tach! I wish the search engine could search for shorter strings, such as model numbers.....

Here's my working machines. The big one has turning brakes and the little one has a solid K301 :biggrin2.gif:

Deputy: I also own a 982. It's an age problem!! My 982 was NOS when I got it and also suffered similar symptoms. So, wuz I you, I'd rebuild/replace the carb, replace/rebuild the fuel pump, and install an inline fuel cut-off. The one below the tank is basically unreachable for normal use, so an inline cutoff where you only have to just barely lift the hood to cut on/off the fuel. This makes it easy to use and , most important, keeps gravitational fuel pressure off the fuel pump diaphram when not in use. BTDT!!. Runs like a dream now!! I'll repeat! Those "rubber" parts in the ONAN carb and ONAN fuel pump deteriorate and die with age!! They must be replaced!

Welcome DeputyRPA!
You have a good one.
You could try using Small Engine Tuneup by PB Blaster and apply it through the spark plug holes and in your carburetor it can make a world of difference.
PB Blaster Lawn Mower Tune-Up

Thanks guys. I'll try the PB Blaster first while I wait for the gasket set.

I gotta say, the 982 with 374 deck mows like a R***d Ape.

Lawn Mower Tune-Up
Eliminates hard starting problems by restoring power and compression to all two- and four-cycle engines. Stops leaks without halting production, and dissipates moisture while inhibiting against rust and oxidation.

Hey Guys..All the chemical magic in the world ain't gonna repair those bad "rubber" parts in the carb and the fuel pump. There are no short cuts or easy way out to rebuild/replace the carb and fuel pump..I've got a 982 with an ONAN B48G engine , BTDT and this is experience with mine talking!! Please pay attention....

Myron B

Oh Myron
He said he was going to order some new parts these are just suggestions to get him by where he can enjoy it till they come in. That Lawn Mower Tune Up additive mentioned in my post sure worked great in my 982 this spring. What happened to you I needed some parts and never heard back from you.

Congrats!!
 

They are impressive tractors..quiet running and powerful..finally got all the parts for the deck on mine(50C), and tried it out..worked great, but might be too large for my hills and dales yard..think I'll leave the mowing to the smaller tractors and make a workhorse out of the 982:IH Trusted Hand::IH Logo::American Flag 1:

Yeah, I'm impressed. I have a few steep parts, mostly my walk-out basement area and my raised leach field, and the weight helps me keep some traction where my Ford just spun.

I have my engine tune-up parta on oeder. I can't wait to tighten it up and close it down, and hear it purr!
