Craftsman 536.886331

Hello. New to the Forum. I have a 20+ year old craftsman model 536.886331. I can't seem to find an engine manual, seems like it may be a 143.941001. I'm not sure exactly what is wrong, but I don't seem to have any spark AND the electric start is no longer engaging. I'm quite ignorant when it comes to terminology, but it may be that the teeth on the starter are broken off? not sure. It just "spins" sounds like "vreeeeem". like it is not engaging on the fly wheel. I've never been able to start it manually with the pull start, ever. Any advice as to where to start would be appreciated. thank you!

Michael, The 143 number should translate into a Tecumseh HMSK100 159244T .

That's a lot of issues for one paragraph, by never able to start by pulling it assuming you mean the pull still turns the engine over?? Starter gear may just be hung up on the bendix and not extending. Also assuming you are checking for spark with the plug out against the head and pulling the rope to cycle the engine?? If this is about right, try a new plug first to see if you have spark. Can't really try to fix anything until we have a spark or at least know the recoil rope can cycle the engine.

Thank you for the fast reply and the links, awesome!

The pull start does cycle the engine, so that it still coupled and seems to be working as intended. I've never been able to start it using that, have always had to use the electric start, unless the engine was already warm and I had shut it down to refuel for example.

I forgot that I already figured out what was going on with the spark The kill key fell out. I just put it back in. so spark should not be an issue any more. Prior to noticing they key was missing ,last night, I kept trying to start it and eventually the starter was no longer engaging.

This morning I found the key, put it back in, I continued to try and start it with the pull, even though I knew it would never start that way. Was desperate to try and get the driveway done this morning. It did just stop abruptly, and that must be when the key fell out. My dog found the key in the snow, and dropped it on the garage floor. quite a miracle actually that I found it.

I think with all that trying to start without the key, I broke the starter.....

Sounds to me the starter drive is not engaging. You have a starter motor with a gear at the end that shoots out when electric is applied and retracts when no electric is applied. This gear could be stripped, or it could not be being thrown out due to being dirty or broken.

Remove the starter, look at it, clean it, plug the box into an electrical cord, press the button and see what is going on. Then two choices. Get another or bring it to a starter shop to be repaired.

For the pull cord, are you saying you can't start the engine that way because the engine won't start? Probably a carb problem then, unless the problem is the pull cord mechanism?

The 10hp is a big engine, I have 2, both start on the first pull in 15 degree weather after priming and choking. I did have a problem with both where they would only start using the electric starter. Cleaned the carb and both start with the cord now.

Yes, the engine just doesn't turn over with the pull start. I'll clean the carb and see what happens. I can live without the electric start if it starts with pulling. thank you!

Just to add on to Clay's information about the engine, your "536" Model Prefix indicates Blower was manufactured by one of the AMF off-shoots like Western Tool, Murray, Noma, or Dynamark who made equipment under the Craftsman label for Sears, and current ownership rights reside with Briggs and Stratton.

I haven't been able to find the starter motor for sale. Seems to not be listed with the other various parts. Again, I can live without it, if I had to, was just curious how much it cost. I'm going to try and clean the carb, and will pull the starter out to see if it is obviously broken, teeth missing, dirty, etc. Then go from there. Would be curious to see how much a new one cost though.

New one is about $125-$150, clone is $60-$75. Do a search on here, someone has used ones, look under the for sale parts, it might be Jack Mel's. You have a common starter.

If you take the starter off, try starting using the pull cord. I use to have a Craftsman/Tecumseh and could never start it with the pull cord (started fine with starter). I had starter problems and took the starter off. Then it would start fine with the pull cord.

That means the drive was not retracting, it could mean the drive or the black box on top left the drive energized.
