I'm looking for some advice on my 886 IH. It starts pretty good down to about 20 degrees or so without plugging it in. Problem is, it runs about 3 seconds and then quits. It will not restart at that point. Only way I can get it to stay running is if I plug it in for several hours ahead of time. Compression is good, as the motor only has about 50 hours on a complete rebuild. 1 hour plugged in isn't enough, 4 hours or so is what it takes for it to start and stay running. Never used to do this. Does this problem sound like an indication of anything specific? Just looking for opinion on where to start in fixing this situation.
