This is a Toro self propelled recycling lawnmower, 6.5 HP. I don't know ho
w old but it looks practically brand new.
The symptoms were: hard to start, dies right away. My brother took it to h
is repair shop twice, they claimed to fix it but didn't, he gave up and bou
ght a new one.
So I took it to my repair shop, one I have confidence in, and paid to have
it fixed for the third time last season. I used it for about one tank of g
as before winter, I ran it dry of course.
This weekend I put in fresh gas. It started on the second pull. And died
before I got about 20 square feet of lawn mowed. Same symptoms as before.
It starts and dies.
I'm not a small engine mechanic which is why I took it to the expert, but I
can swap a part. Any ideas where to go next? I don't like to think of l
awnmowers as consumables; if maintained and not abused they should last nea
r forever in home use. Maybe a lawn service would wear one out but not me.

First question would be what was diagnoses as the problem on all the other
pro repairs? It's very common for carbs to be a problem on these small
engines due to ethanol gas. Some, for whatever reason, are more susceptibl
than others. If it has compression and spark, the carb and fuel supply,
eg filter in tank, kinked hose, are the remaining prime suspects.
You can buy a rebuild kit for many carbs on Ebay for less than $10.
That gives you gaskets, needle valves, welch plugs, etc so that you
can completely disassemble the carb, clean it, rebuild it. You can
do that without the kit, but if it has welch plugs, you can't get to
all the passages without taking those out and then you need new ones.
Still, you can probably clean 90% of it or more and the areas behind
the plugs may not be the problem.
They also have many aftermarket replacement Chinese carbs for maybe
$20. I recently bought one for my leaf blower and it runs better than

I didn't know that. I have actually rebuilt a carb for a car I owned, but
it's been nearly 50 years. My kids have never seen one. Come to think of
it, my auto mechanic has probably never seen one. But rebuild kits are fid
dly if the model isn't exactly the same, I'm better off getting the whole c
arb for $10 more. Thanks, worth a try.
I had a 6.5 Toro Recycler < not self propelled > for ~ 10 years
and the best thing about it was the engine. I scrapped it when the
frame rusted out. I would have squeezed more years out of it -
except it was such a frustrating machine for clogging -
even in side-discharge use ..
What engine? does it start after sitting for a while to cool off? Did
you try running withthe fuel cap loose?
It's either fuel or spark.The ignitor/coil unit can fail when warm.
The fuel cap vent can be plugged. If it runs well than quits it is
unlikely to be a carburetor problem - but not impossible. I'm
assuming it is a flat-head Tecumseh or Briggs - not an OHV Chonda
Not sure what engine the OP has - the B&S 7 HP in this video
looks like the 6.5 that I had - I never had a bit of trouble with
mine - started first or second pull for 10 years or so.
... maybe 3 pulls for first start in the spring.
I hated to junk a good engine, but I didn't like anything else
about that mower.
I found a little Jacobsen/Homelite for $ 25. at an auction -
looked like it had sat unused for some years - and after
cleaning the carb it works like a champ !
3.5 or 4 HP B&S Quantum ; aluminum deck.

I have ar early 80s Toro recycler - cast deck. It sat for over 20
years and starts very well. The owners had a lawn service do their
lawn for the last 30 or 35 years and finally decided to get rid of it.
I had a weed whacker the showed the same symptoms. Gave it to my son, who found the hose
from the gas tank to the carb had dissolved/melted enough to restrict the gas flow.
He put on a new hose and then it worked fine.
Some of the early Briggs side valve engines suffered from a magretron
unit that failed when warm. Not at all out of the ordinary. If it
starts and runs for ANY time at all, it's generally NOT the carb.
The OEM coil unit runs $40- $50. Aftermarket replacements are
available for about $17 - $20US
