Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you're having with the drain extension leaking. I know how frustrating that is to have happen.

You could have slightly stripped the threads on the extension. Unfortunately, the drain extension is no longer being offered as a replacement part on this Tecumseh. I would recommend using some Teflon tape around the threads on the extension. Use a liberal amount of tape to make the fitting nice and tight on the extension. The thicker the tape is applied to the threads, the better the seal it will offer. I would try that first. 

Outside of that, you could have the block of the engine tapped out for new threads, but you wouldn't want to go larger than what it currently is, unless you could put a larger drain or plug in its place. I would try the tape first; it works well in those types of situations. 

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

Hello glad to help.  Thank You for choosing Sears PartsDirect.com
 
I am sorry and do understand your frustration when there is trouble with the engine not starting. 
 
Glad to help out.   Im  looking at your  Craftsman model  number 536.887251.  Using the model number, I found the original engine model number 143.025501 which is what Im using.

The part number for the carburetor as a whole, complete unit is 640084B.   Most of the time when the bad gas has been in these and they set for over a year then you need most likely to just replace the carburetor as a whole unit. Saves time, hassles of taking apart, trying to clean it and putting it back together just right.   Then find out it doesn't work still.   

I did however find also a carburetor repair kit which is part number 632760B.   

I'd take a few pictures for the hook up of the hose connections and the throttle connections before  you take it apart so you have some idea on how to get it all back together.

Recommended to use in all small fuel tanks is Fuel stabilizer.   IT cleans the system out and guaranteed to be good for a whole year.   Never let gas sit in a container over a month because the ethanol gas is bad when you get it new and gets worse when you let it set.

If you go to www.partsdirect.com and put in your model number of the engine 143.025501 then you too can see the parts.   Wish you luck.


If you have further questions please let me know.
Thanks for choosing Sears PartsDirect.com

Went to You Tube and saw how to take out the drain in the carb bowl. I did that and siphoned out the old gas. Put in new gas and it started right up with the pull rope. I do use fuel stabilizer in all my small engines and my scooters but I bought the snowblower used. But it had never been started. The guy put gas in it but never ran it. But now I've got another problem. Initially the electric start worked but now nothing. I plug it in and push the button and nothing happens. Luckily it'll start on the first pull of the starter. Bad switch ? Is there anyway to check that ?
