Engine john deere 260 lawn garden tractor

[slickstick260]

I have 260 johndeere lawn garden tractor. What it is doing it,s eating the choke bracket and the screws.
This kawasaki engine has done this twice.Is there something that i can do to prevent this doing this again. You,re inpute would be very grateful.

slick, Please explain "eating." My Intek ate its pushrod after dissolving its exh cam. That gave it a severe sump-ache and it then refused to run on the affected cylinder.:smile:

What i am saying is the choke shaft breaks off . Then the screws and the shaft gets sucked in to the pistion as well the head. Thank you for you,re respones.

slick, If you can, post a picture. Otherwise post a drawing from " a manual." There are many on the forum who would like to solve your problem if you can give us more information. If you cannot post, then tell us where the choke shaft is breaking and what it is made of (brass, steel). Also (I'm not familiar with your model), is it a slotted shaft with a round butterfly held in with staked screws? Sometimes when a post is "bumped" like this one the information will flood in to help.:thumbsup:

The choke shaft is metal and yes it does have two screws brass screws to hold the butterfly on . Two the choke shaft the # onthe engine is (fc5404180796).
The engine code is (fc5404-d500).I hope that get, s a picture of what it looks like. The tractor id# is m00260T102246. Please sone as possble. Or i can put a Briggs &stratton on it with a #28707/ type # 0220-01 code# 9502104a it, is a 14.5 vertiacal engine. The other piece of the puzcle is wirring system. to make the briggs engine work. Thank you for response.

slick, Since no others who have the model are responding I will wing it just based on my understanding of how chokes "used" to work. The butterfly is not normally totally closed in the throat of the carb. Otherwise when you pull the cable the lever will wind up further than it should because a stop of some kind is not working to keep the butterfly from contact. If the stop you feel when pulling the choke is, in fact, the butterfly against the carb throat, then each use may be stressing the shaft where is rests in the shaft bore near the crank. Repeated stress will work harden the shaft so it eventually breaks off.

You have said the engine is eating stuff. It is hard to imagine the engine surviving if , somehow, the butterfly comes loose with its staked screws, and enters the combustion chamber.
I have not tried to search out your PN drawing, because I was sure some JD enthusiast would respond. Perhaps they still will, if nothing more than to stop this theorizing.

Have you actually replaced choke parts that have entered the engine? Look at the choke shaft outside the carb for a stop of somekind that is either broken , missing, or not adjusted.:smile:
