Toro Recycler mower w/ Tecumseh 6.5 engine - starts and immediately dies
 
I picked up a Toro 22" Recycler mower from the curb a few days ago. It looked relatively new and visually fine. It's got a 6.5 HP Tecumseh engine, model LEV120361560B. The spark plug looked pretty new, as if the previous owner had just replaced it. Wouldn't turn over. I drained the old gas, monkeyed around with it a bit, and got it to the point that it will start and then die out 2-3 seconds later. Today I went to get a rebuild kit for the carburetor and rebuilt it. It's no better than it was before the carb rebuild.
Any ideas on what else I should be checking on this mower? My knowledge of small engines is very limited..part of the reason I'm doing this is to learn from the experience (and, of course, to have a running mower!)

Thanks

A nice little project that can drive you crazy. Following site is pretty thorough and should give you much of the info you need. Post back with your progress.

Been there....
 
Spent my whole summer, literally, trying to get my Toro 22" Recycler bought Aug 2008 to work. Went through everything you could possibly imagine...would take me 30 minutes to type the whole story. The shop had it more than I did this summer. I think the Toro Personal Pace is the best drive out there....but Toro does make its share of lemons and I got one. Mine is a Briggs and Stratton engine.

As part of the carb rebuild did you replace the intake gasket?? That's what it ended up being for mine..and this was done as an in-warranty repair at a local shop....after several other in-warranty repairs earlier in the summer....They replaced and/or doubled up...not sure which...the gasket between the intake/throttle body and main engine. I've heard tell that those sometimes warp or have issues...especially after heating up. This was done to mine I think sometime in August and it's worked fine since. Whereas before it was finicky as all get out...especially in taller wet grass. Good luck and keep us posted.

I bought a zero turn from a buddy this year that couldn't get it to run for $200. There was a fuel sut-off solenoid that had lost power due to a burnt wire. Took me about 30minutes to diagnose, fix, and start mowing. After a couple weeks, it would start dying after about 10 minutes, if it sat unused for a couple of days, and when I would fire it up it would die in a matter of seconds. I piddled with it on and off for a couple weeks. I checked everything and couldn't find a thing wrong with it. In an act of desparation, I unscrewed the fuel cap and looked inside with a flashlight. Lo and behold, a dead ladybug was in the bottom of the tank. I fished it out and never had another problem. Check for lady bugs!

When you rebuilt the carb. did you open up the filter bowel for the gas? those bowels like to fill up with debris and water and will cause those surges...perhaps checking that out may help you.

Pickngrin 10-16-2009 06:29 PM

Thanks for each of the replies. Fortunately (or unfortunately, as it would have been an easy fix), there were no ladybugs in the tank!
Today, I change the gasket between the intake valve and the engine block. No change in engine behavior -- it still starts and dies almost instantly.

Funny thing, a few days after finding the Toro Recycler with the Tecumseh 6.5 HP, I found another Toro Recycler at the curb in my neighborhood, this one with a Briggs & Stratton 6.5. I figured between the two mowers, hopefully I'd get at least 1 running well, but maybe both. Well, the Briggs engine started up but gave off heavy white smoke. Turns out the previous owner had too much oil in there. Today I removed the carb bowl and cleaned it. Replaced the air filter. Starts up beautifully now, with barely a tug on the cord! So this one is running nicely, but I haven't figured out the problem with the Tecumseh engine yet.

Viper asked if I opened up the filter bowel for the gas? Do you mean the bowl under the carb? Otherwise, I am not famiilar with a filter bowel, and didn't find anything when I just Googled the term.

Thanks again

Yes, that bowl. Try to remove the bowl, float, and needle valve. Spray Gumout carb cleaner up into the hole the needle valve sits in to get rid of any debris/build up that may be gumming up the works. Reinstall and try again. Have to assume you are getting spark (does it get wet after a few pulls of the starter? Right plug?). Choke/linkage adjusted correctly? Mixture and idle screws at right settings?

Oh, OK. When I did the rebuild, I disassembled the bowl, etc., sprayed Gumout, installed a new needle, etc. I am getting spark (I used an inline spark tester to check). I don't see any mixture or idle screws on this carb. I believe the choke/linkage is adjusted correctly, but last night I was looking online for a picture of how it should look.

Ok, I got the Toro with the B&S engine running like a champ with a minimum amount of effort, and I was getting frustrated with the Tecumseh, so I listed it on Craigslist and sold it the same day. I'm happy with the outcome.
Thanks for all of the input and suggestions.

Nothing like selling off a problem; best fix of all!

:-) Well put!

Changed the spark plug and cleaned carb on mine now it runs great.

I cleaned the carb then got one good mow and it started dying again. After cleaning the carb AND replacing the spark plug it works fine.

BTW on second carb cleaning there was varnish build up again.

YMMV

Bizarre timing...I just came in from mowing the lawn. This is a different mower - a Toro Recycler 22" but with a Briggs 6.5 HP engine.
The mower was dying again, every few minutes. I was just about to look up this site and post a message, and I had email that there was an update to this old thread!
I took off the carb bowl and reinserted the metal piece that closes the needle valve. Then it started right up...and died a few minutes later. It seemed like the engine was decreasing in power as I was mowing, too. Any ideas on what I should do at this point?

Thanks

mower
 
My experience with it so far has been:

1) Mower ran great for 2 years. 3rd season it started dying after about 5 minutes of run time.

2) Cleaned carb, visual varnish lumps on inside. Ran great for one more mowing session.

3) Cleaned carb again. Ran for 5 minutes and died.

4) Changed spark plug. Runs great all the time now.

I have the same one. I finally broke down and pulled my carb apart for cleaning...first carb work for me. Runs better after carb cleaning and change air filter. But that doesn't last long. Don't really notice anything gummed up when cleaning carb. But seems my Toro expects a carb/filter cleaning every month or so. IMO the Personal Pace system is the best out there but the Briggs engines on the Toros are total crap. I'm gonna see how it goes but thinking I'll use the same strategy as Pickngrin in the near future. Thinking I might try a Toro commercial version next. The thing that gets me is these carbs are total crap....and the fact that they work well for a short while after cleaning lets the dealers exempt it from warranty coverage...."fuel issues" aren't covered. Even though the REAL root cause is a design flaw. Well...at least I know how to clean a carb and can avoid having to pay the local guy $40 every time to do it. They indeed don't make them like they used to.....
