Different kind of Starter Problem

[buriboi]

Hello All,

I have a 2 year old Craftsman gas mower. When I start it up, it works perfectly and always starts on the first pull of the ripcord. However, if I then stop mowing for a minute or two and try to *re-start* the engine, it cannot be done. Generally, I have to wait about an hour or two before it can be started again, at which point it works perfectly again.

Any suggestions would be appreciated!

And what does this mower look like. Without a model number for the mower as well as the engine, I have no way of knowing if you have a 20,21,22 inch, self propel or not, with a MTD engine, briggs engine, kohler engine, or honda engine.

Good point!

It is a 21" Craftsman mower, only model # I can find is 944.369100.
The engine is Briggs and Stratton, 650 Series, 190 cc, with 6.5 ft lbs of torque.

Hopefully somebody can offer some advice now!

Somebody already provided me with this brilliant advice via private message: "pull harder, woosie". Lol. Any better advice out there?

don't you just love smart alec answers to real problems. I tried looking up the model number that you gave, but couldn't find it. I don't know if posted incorrectly or what, but I will take a stab at it. If possibly try to find the model number off the engine, should be either stamped into the housing just above the muffler on the flap that sticks out, or may be stamped into the metal housing above the spark plug, may need to either look up under a plastic cover, or remove the cover to read the numbers.

I am going to make an educated guess and say the engine has the ready start system, which is an automatic, thermostat controlled choke, I suspect the choke is reclosing when you shut the engine off, instead of the thermostate holding it open for a warm restart, which causes the engine to flood when restarted warm. Next time you shut it off, remove the air filter cover and see if the choke is still open or has closed. If it is closed, then the thermostat mounted behind the muffler is faulty and will need replaced.

The model # of the Briggs engine is : 124T02-1335 B1. Maybe that can help you confirm one way or the other!

Thanks for the input so far

The parts diagram shows both the ready start/ auto choke, and a primer system. If you don't have a primer, refer back to my post about looking at the choke, to see if it is still open right after you shut off the engine. If it is closed, it will float the engine when you try to restart the warm engine. If the choke is open, then there may be a carb problem causing it to run lean, and not get enough fuel to restart.

My mower does have a primer...Do you mean that the same engine comes in two separate models, one with a primer and one without?
