Cub Cadet 1250 problems

[Camo-Man 07]

Well I'm back again

When I was out "joy ridding" in my back yard she stated to backfire like mad and tried to die on me. I shut her down for a few minutes then started her back up. Ran for a little then started to sputter and tried to die. I manged to limp her back to the garage(start stall the whole way) I thought the points might have slipped so I reset them.

When I tried to start it she would start for a second then die and I'd get a puff of smoke from the carb. She fires then kicks and dies.
Right now it will spin and spin but it wont fire. it has spark. and it will kick once then smoke

Any suggestions?
Thanks for any help

What engine is i it? Courage Kohlers have known problem with flywheel key; it will look good, but you need to pull flywheel and inspect it and probably change it. It throws timing off.
Could be a fuel delivery problem. Filter, ice?

Okay; not a courage motor; try a new spark plug.

Valve spring?

Make sure nothing is grounding out ignition

 

[Camo-Man 07]

All the ignition system and spark plug work, I made sure of that before I posted.
Although maybe a new plug is in order, its worth a try and its cheap.
Its a Kohler K301.

There seems to fuel getting to the carb, however I was thinking that I might need to make adjustments to the carb, maybe its either not getting enough or its getting to much and flooding.

Is the gas good or maybe has dirt or water in it?

Carb settings: Low 2 1/2 Hi 2

The gas is good, there shouldnt be dirt in it but ya never know.
Thanks for the carb setting. I'll do that tomorrow, too cold to work on it tonight

 

[dqdave1]

As I reread post; you stated it is backfiring through carb. This is an indacation of timing off do to flywheel key, ignition module, valve spring or bad plug. Could be a ignition ground wire pinched or touching also.

 

[Camo-Man 07]

I'll go with replaceing the spark plug first, its the easist and cheapest problem to fix.

Its a 79 if that helps any....

Just some more info on the Tractor.

There is a strong spark and the plug is wet when I pull it out. But it will no longer start, at all. before it would kick once or twice then stop. Now it wont do that, it just spins and spins until it drains the battery. No kick at all. I even tried starter fluid

 

[dqdave1]

Strong spark - wet plug? ; could be bad plug or too much fuel or timing issues.

 

[Camo-Man 07]

Timing is controled by the points and I have those set right, 0.015 and that is what I was told to set them to, and it had ran with them like that. And the spark is nice and strong from the plug. I'll see if I can fix the flow

 

[2manyrocks]

I think I may have given you the wrong carb settings. Sorry. After reading the manual again, if your K301 has a Walbro carb, the low setting is 1 3/4 and the main idle is 1 1/8. Also, the manual says the points should be set to .020.

If you have a strong spark and a wet plug, it ought to run.

 

[dqdave1]

Timing can be affected as follows; keyway on flywheel gets loose or begins to shear. Magneto out of adjustment. Valve spring broken.
Do you have compression?
Will it fire with starting fluid?

 

[Camo-Man 07]

I'll reset the points to .020 and try again. I have the Kohler carb so we're good there.

If it dosent run I might just give up on it till summer

It wouldn't fire with starting fluid.

How would I go about checking the flywheel, and what should I look for? I don't know all that much about engines yet.
Also how would I check the magneto and the valve springs?

It wouldn't start after adjusting the points again.

I do have compression, I just put a new head gasket on it

 

[dqdave1]

If it will not fire with starting fluid, you have an ignition problem. I would change the points and condensor; do not use chinese junk points. Buy Kohler points and condensor. Set them at .020. It should run at these settings. You may have a coil problem also.
This is an interesting problem; you have everything you need to run; spark, compression, fuel.
I would put another plug in it if you did not do it yet. Stop by your local Kohler dealer and explain it to them. When you go; take coil, points and condensor and plug with you so they can look at them. Get their opinion on them. ( hopefully they have a good mechanic.)
Good luck.

 

[Camo-Man 07]

I just bought new points condencor and coil. So I'm going to get a new plug and see if that fires. if not I'll be doing what you said and taking it to Kohler. If they can't do it, I'll eat the battery

 

[dqdave1]

Are they kohler parts or aftermarket parts? Just saw a problem with "cheap" parts that were junk out of the box; almost same problem as you. these Kohlers are good most of the time, seem to run forever. Coils go bad at about 500 hours but that is 50 million plug firings.
Did not know if you had a manual; so here is one for you.

[Camo-Man 07]

Yes I bought Kohler parts.
I'm gonna hook the charger up to it tomorrow and try starterfluid again.

The strangest thing is I used to have no problems with it before then head gasket blew, but it was old so I didn't think much of it. after that I started having all sorts of problems. I replaced the head gasket, then started having ignition problems. got that sorted out and had point problems, thats why I got new condecer and coil along with the points. After that it ran for a few days, after that it backfired and died, now it wont start at all

Thanks for the manual

Try and remove cowling, etc to expose the flywheel. Remove bolt that holds flywheel on along with washer. Look closely at the keyway; does it look like it is in good condition? If you want; put nut back on till it is flush with end of crank; usinfg a piece of wood and a mini sledge; rap the nut; it should loosen flywheel so you can remove it. It will take a good rap to free tapered shaft.nNow you can examine keyway.

Sent you a PM.
