Hi Folks,
Having a strange problem with the mower. It's a 2010 Toro Recycler with a 6.75hp Briggs engine. Starts fine when it's cold and runs good, but just doesn't want to restart when it's warm. It's my father's mower and he has had this problem since last summer. So he took it back to the place he bought it from and they supposedly cleaned the carb and thought it was ok, but it's not. I brought it over to my house and took the carb off and took it apart. Pretty clean inside but I cleaned all the passages anyway with carb cleaner and blew them out with compressed air. I didn't notice anything wrong so I put it back together and back on the engine.

It started right up with one pull and ran great. So I let it run for about 2 minutes and shut it off. It restarted again, but not as easily as the first time. I let it run for about another minute and shut it off again. This time it would not start. So I shot a little gas into the carb and it fired up and seemed to run ok. But every time I shut it off I'd have to do the gas squirt to get it started again. BTW, this carb does not have a primer bulb. The auto-choke was closed when cold and then fully open by the time I ran it for about 4 or so minutes.

The model number stamped in the blower housing is: 126T02-0299-B1 10081659 if that's of any help.

Any ideas?

I'd check the float in the carb bowl to make sure it's not stuck. Also, try running without the gas cap on to rule out a clogged vent.

these carbs are JUNK. if you want to solve the problem, buy an old style air cleaner housing used and prime it instead. the problem with these carburetors are that the autochokes dont work properly.

The auto choke or "ready start" can be a pain and I wish they would have stayed with primer bulb....but probably more epa crap.
THere is an adjustment tang you bend on the heat riser behind the muffler to adjust how quickly it opens the choke.

Yours seems to be the oppoist of what many do.
Most get warm and if you turn off for just a couple -5 or 6 minutes the choke closes too much and they flood out.
Yours isn't getting enough fuel.

If it runs perfect and you can rev it up manually with finger on throttle on carb after it restarts then I say your carb jet is probably clear.

I would take shroud off and work choke heat riser moving arm back and forth. Then apray the heck out of t near the bottom behind muffler with wd-40 or pb blaster etc and work if to and fro.
Then make sure the tang at end is somewhere in the middle of adjstment and not all the way expanded open wheich is IIRC the way it would open choke faster farther.

There is also a smal diameter spring about 2 iches long that holds the auto choke closed. It is hooked to metal loop in shround piece and then to plastic hook on choke arm.
Check it first.
It could be missing. That will give similar symptoms. I find them missing evey now and then and had one that the hook on arm was snapped off.
IT could aslo be stretched out and not closing choke hard enough.
