k321 hard to start in cold weather

I have a tractor that has a k321 14hp kohler. The first few years I owned it (6 to 8 years ago I got it), I just hit the key and it ran. Now, when the weather turns cold, it just cranks and cranks and, unless I put a small heater on it for a while, it won't start. In warm weather it starts up like it always did. Could this be an ethanol thing? It cranks strong so the battery is not in question.

I said I work on them; I never said I fix them!

Re: k321 hard to start in cold weather

Did you check to see if the choke is closing all the way inside the carb ???

You know, I haven't. The cable is pretty hard to pull so maybe it's hanging up in there. So simple I blew right by it. Thanks Kevin, I'll look tomorrow and see what's what.

Re: k321 hard to start in cold weather

I had the same problem (12 HP Kohler) and replaced a spark plug to coil wire and that solved my issue.

Sounds like that will be step 2 then. Thanks.

Re: k321 hard to start in cold weather

The old wire was "leaking" electric really bad I inadvertently touched it while the engine was running and got lit like a Christmas tree! That is what told me it was time for a new one!

Re: k321 hard to start in cold weather

It's chilly here this morning (low 40's) which was the perfect time to try this choke thing. I went out to the shop, took the air cleaner cover off and worked the choke a little. It looked as though it was closing all the way but it wasn't quite getting there and the cable was pulling very hard. I took my finger and closed it the rest of the way then did a cold start. It cranked once and it was running at an idle. I guess it doesn't have to be open much to make a difference. I hope to get a new choke cable at lunch time today and I think I will go ahead and replace the plug to coil wire while I'm at it. Can't hurt and, if anything, I'll have a spare. I'll report back when all this is done and I'll either have good news or more questions. Probably won't get to it until the weekend. Thanks guys.

Re: k321 hard to start in cold weather

Looks like we have a winner. I put the new choke cable on tonight along with a new wire from the plug to the coil. As it turns out, I didn't have to do the wire but, what the heck, winter is coming so it's better now than when I need it. Fired right up. I moved it out to the barn and will give it another go int he morning just to be sure but I think we're good to go. Thanks everyone! These simple little things can really get you sometimes.

Re: k321 hard to start in cold weather

Well I thought it was fixed. I tried to start this thing yesterday and it cranked and cranked and then back fired. After that, it started and ran fine. I'm starting to think I need a carb rebuild. How much play around the throttle shaft is considered too much?

There should be no play, I had several, B/S and my K321, Makes starting hard, and you can't get to idle right. I was able to locate a brass bushing at T/S and dremel it to replace the old one.it fit in the recesed part on the carb. I heard some don't have this recess. Then a new throttle shaft should fix it.
