Jinma 284 sputter and stop

I am posting in hopes this helps someone. Many others have helped me many times in these forums.

I have a Jimna 284, about 17 years old. While plowing the road today, the tractor started sputtering, picked back up so I continued to plow. About 2 minutes later it started again, and really acted like it was going to stop, so I killed it.

I totally forgot everything about the tractor, and ran to the forum to start looking. I read several posts about many fuel problems, so I checked all the typical thing, filter, bowl, color of fuel, smell of fuel…All looked good.

I figured the worst, but primed the pump and when I loosed the bleeder ring while priming, I thought I saw some air bubbles. As I primed flow was good, so I tightened the prime and started. Was running pretty good for about 2 minutes when it sputtered again.

Did the prime again and checked the bowl a bit more. I noticed the bowl was easy to turn. I turned it a bit, about finger tight, primed and fired it up. Ran like a champ.

It is way too cold out there to fool with it more tonight. I am hoping to get it into the garage this weekend and get a closer look. I am thinking there is a seal, O-ring or something that needs replacing.

If anyone has some pictures of it pulled apart, please send along. Else I will post some when I get a chance to work on it later

In any case, it is good thing to check if the happens to you.

Thanks
Jerry
