Toro Recycler mower w/ Tecumseh 6.5 engine - starts and immediately dies


So.....
You've installed the new spark plug.
You've installed a new air filter.
You've cleaned the jet on the nut which holds on the carb bowl.
You've tightened the two bolts VERY GENTLY which join the carb with the manifold.
You've made sure the gas tank is clean and has fresh gas.
You've changed the oil and put in the proper SAE 30W oil (20 oz.)....

AND THE MOWER STILL STARTS AND THEN DIES!!???

DO NOT MELT DOWN JUST YET!

I had this problem and I think I found the formula for the long term fix. If you have the skills and tools to take off the red cover AND the black metal cover which houses the start cord mechanism - here's what you do:

First, take a small wire brush (a 1/2" copper fitting brush works very well)and clean off the magneto surfaces on both the coil and the flywheel. If you don't know where this is, just follow the spark plug wire from the spark plug up to the coil and there it is. There is one surface on the flywheel and three surfaces on the coil.

Secondly, there is a very short black hose leading from the carb to the engine which you cannot get to without removing the black metal cover. This hose comes from the factory without clamps, and from what I could figure out, with age this hose loses vacuum when the engine gets warm and the hose expands slightly. That's why the mower will run fine for a few minutes and then all of a sudden after the hose warms up a little, expands and loses vacuum, the mower does the start and die routine which we all know can drive you nuts.
Get two spring-type hose clamps which are identical to the ones attached from the gas tank to the carb. These are available at Ace hardware for around 40 cents apiece and they are 1/2" O.D. size. PUT THESE CLAMPS ON THE SHORT BLACK HOSE. This is the "secret" ingredient to the long term fix.

Put the covers back on. Don't overtighten the bolts. And get back to work!

Personally, I do not like Tecumseh motors. Every one I have had I have spent countless hours trying to get it to run. One mower, no matter what I did, needed starting ether. After I got it started, it ran fine. I will only buy a lawnmower with B&S, Honda, or Kohler motors. Well, I should say I won't buy a Tecumseh.

I am having the same problems with my Toro Recycler with the B&S motor -- stalls after starting -- I can pump the primer and keep it running. This happened last year and I cleaned the carb. and it ran fine for one year and now have the problem again --- poor design!

I am going to try a fuel injector cleaner in the gas and use the primer button to keep it running in hopes it will clear.

I will post if this works.

thanks,

Joel

FWIW...after several carb cleanings using other products...I did a thorough cleaning and soak with B12 Chemtool in early spring...mower has been dead on reliable all season so far.

Agreed. My 21 yr old Honda walk behind starts on one pull. I don't even need to worry about the gas during the off season. It will start on varnishy crap that will kill my other mower.

If you can't afford the HONDA , use my hose clamp fix. It works. My mower is still running strong and has had no other issues with gas or cleaning or whatever. The mower has had absolutely ZERO problems since doing the simple, low cost fix and starts EVERY time on the first pull. I just want everyone to know it wasn't a fluke and the fix is a true fix. Cheers.

My toro Briggs / Stratton engine never would start after I got it brand new. Turns out the spark plug wasn't tapped properly. It starts on the first pull still after 7 years. Love that thing.

Tapped, or gapped?

Toro Recycler mower w/ Tecumseh 6.5 engine - starts and immediately dies


One thing I have not seen mentioned here is ignition timing / flywheel issues. I have an older B&S Quantum mower. My house was abandoned when I purchased it, and I used the mower to clean up the yard. At some point, I hit something, and stalled the mower out. Well, this shears the flywheel off the key and knocks the timing off. The ignition timing is good enough to start the engine, but as soon as it gets spinning, it will be too far off for it to stay running, and it dies. My (new at the time) neighbor saw me cussing and swearing at the mower (which previously ran great) and he came over to help. He said that's a common problem with B&S motors if the mower hits something. He helped me disassemble it, pull the flywheel, and re-time it on the crankshaft. That was 10 years ago, and the mower continues to run great!

I am having this some problem with my Toro mower with Tecumseh engine. It will start with three primes and stall after a few seconds. If I hold in the primer it will continue to run. I have changed the spark plug, replaced the gas cleaned the carb, put hose clamps on the hose between the carb and engine. I guess the big difference between the other post and this one is the fact that if I hold the primer bulb in it continues to run. Any ideas?

the nut/bolt that holds the gas float bowl up has a small hole in it.the gas goes up and out into the spark plug any slight sliver of grass will stall you out after start ups...clean out with a sewing needle

I cleaned that out as part of cleaning the carb. I cannot understand why it runs by holding in the primer button. I don't know the inner workings of this particular carb.

Replacing the primer bulbs helps sometime,checking the float level helps too but what really helps is giving up,either it works or it doesn't when it comes to Tecumseh.
