New 982

[deputyrpa]

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) 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

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.

This can't be right.....

No the wheels are not correct.

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?

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....
