Ok the story goes like this. I made my usual trip on my JD314 K321 to the coffee shop yesterday pulling my cart taking a borrowed welder back to my neighbour on my way. I left his shop got to coffee shop. Shot the bull for a couple hours got on my tractor it started just fine idled for about a minute while I talked to a friend. It died and hasn't hit a lick since. I have spark, fuel pump works good, fuel in carb bowl. Has compression. So I reinstalled the plug. Still no start. Removed plug again and I noticed the plug was dry and it should have been wet as much as chocked it.
Any help would be appreciated.

I'm going to bed, goodnight to all

Thanks

larryd

Larry It sounds to me like something is just blocked in your carb. Do you have a fuel filter on this?

 

From all you have said, I don't think you have anything seriously wrong.You could always try shooting some carb cleaner in the throat of the carb 1st to see if she fires off.

 

I just think since it was running fine, there were no strange noises, you have spark and you know you have fuel to the carb, then that points in the direction of just a stuck needle vale or one of the small ports in the carb has a piece of junk plugging it.

 

Good Luck!

Died?  That will need a BIG BIG hole to bury it!  That's what I do with all our pets when they pass on! Happy Digging. A few beers will be helpful and final words when done! :rolling:  :beer:

How much compression??  Did you use a tester??  May be a cam or intake valve issue..

Hi Larry,

 

if the engine has compression, the spark works and is try (or wet), it must be the carb. And a fuel filter is always helpful.

 

EDIT: always remember, nothing runs like a Deere ildeere.gif

Ok I didn't test comp with tester but it will blow finger off plug hole. It has an inline filter and lots of gas comes out of line at carb inlet when turning over. Bowl was full of gas so needle wouldn't be stuck. I don't think it is valve or cam because it was running fine and just shut off no noise's. I did spray cleaner in throat a few minutes ago and it didn't even attempt to fire . That doesn't sound good.

Then maybe the spark plug doesn't work right. Sparking alone isn't enough, the heat is important (hard for me to explain) and testing the compression with the thumb is not the right way :smilewink:    It's a pity that you live so far away... :wave:

Larry, do you have a nice snappy blue spark? If the plug is dry it sounds like you aren't getting any gas. If you put your hand over the carb inlet does it produce a vacuum when cranking. The valve action can be viewed by taking off the small cover where the PCV breather tube exits.

I would suspect that you got a little water in the gas. If a small bubble of water forms in the fuel bowl of the carb it can temporarily kill the engine. Try a little gas directly down the carb and see if it runs. Sometimes this will also suck the water through and solve the problem. That is why sometimes a GT will die, you leave it for a day, the water evaporates out, and then it runs fine. Good Luck, Rick

My votes are contaminated fuel (dirt, water, etc) mucking up the carb or the spark plug says "Champion" on it.

You need to check your points and/or condenser.  Just because you have a spark doesn't mean it is hot enough to fire in compression.  Take a points file and clean up the contacts.
 

Is your governor spring right?  Did it break?

Hi Larry. If you have fuel in the bowl but none making to the engine , first I would put a little fuel directly into the carb and see if it fires. If the engine fires, I would check your main jet in the carb where it picks the fuel up to make sure nothing is blocking it. Some pickup tubes have two Inlet holes at the bottom , others have the two inlet holes in the bowl retaining screw wich all need to be clear. Hope this helps

I'm with Allen on this one, Try a different plug. I lost one in the middle of the parade last weekend at Plain City. Got pulled back to the show, swapped plugs and it fired up on the first spin.  :wallbanging:
