Can\'t keep the engine running...
Okay, here's one for all the International experts. First, let me give you the background.
I have an International 424 with the C-146 gasoline engine.
No problem starting the engine, but, for the first few minutes of operation, the engine sputters, misses, tries to die, and/or pops out through the exhaust when under a load. It'll do this until it eventually evens out, then usually runs fine. I cannot advance the throttle to full, or even 3/4 speed until it works this out.
Now, I'm having trouble keeping it running over 15 or 20 minutes. When trying to mow, it started, went through it's rough wake up time as described above, but, seemed to fall back into that routine when under a load. (I was mowing, 5' bushhog, pretty tall grass). Seemed to run poor especially when under increased load (up hill, thick patch of grass. etc.) It then ran fine for 15 or 20 minutes, not sputtering under load, or any other unusual issue. Then, about 20 minutes into the operation, it just started sputtering and died. It wouldn't start back for about 15 minutes, when it did start, it would fire right back up, and go for another 20 minutes or so.
The last time it started to sputter, I stopped, and tried to advance the throttle to full speed without load. It would not run at full throttle, I'd have to back it down to idle, and slowly move it up. It would start sputtering and want to die around half throttle. It finally died and it stayed where it died overnight. I'm sure when I go out, it'll start, and run for 15 - 20 minutes just fine.
A few things I've looked at:
Radiator is full, seems to be circulating OK. Due to the fact it runs poorly at start up makes me think it's not an overheating problem. No steam venting or coolant purging when it's been running hard and dies, and no smell or noises like it's too hot.
When it dies, the first few times of trying to start usually end with a delayed pop out of the muffler. I figure this is fuel getting pushed out of the cylinders and igniting in the hot muffler, so I assume I've got fuel. I just let it sit for a while and it starts up.
I took off the distributor cap, and it appears dry, and rotor button looks ok, but, I'm by no means an expert on the ignition system.
So there you have it. All you old International gurus see what you can make of it.
