IT COULD BE, SOMETIMES WE OVERLOOK THE SIMPLE THINGS

If it was the gas cap, the engine would start, run fine for a while and then stall. It would not exhibit a no start condition, and it would run great when the gas cap was loosened.

Ordered the new carb. We'll see in a couple days whether or not this solves the issue. Will let you know. Cross your fingers....:thumbsup:

It Works!!!!:smile: Awesome diagnosis and assistance!!!! It now starts on the first pull. It hasn't done that since the mower was new. Only one tiny issue, the attached pic is a small part that fall off and I am not sure where it goes. ???? Thanks again....

Yes!!! :thumbsup::biggrin: Glad it's working now! That was a hard one to diagnose. Briggs carburetors are typically easy to clean, maybe yours had something else wrong with it. If it was a Tecumseh engine, replacing the carburetor would have been my first suggestion. Tecumseh carbs are nearly impossible to rebuild correctly.

Don't know where the part came from though. I'll take a look at my Toro tomorrow and see if I can figure out where it came from. (If I remember, that is. Don't hesitate to keep reminding me. :laughing

Excellent thanks. I am thinking that the part came from the air filter area but am not sure.

Primer,,

Checking in, any luck figuring out where the pictured part went on my mower?

 

[primerbulb120]

Haven't got a chance to check my mower yet. I did look up the parts list and I'm not seeing it.

I think it's either

A. Not part of your mower
B. A broken piece from a larger part.

Keep reminding me and I'll eventually check my mower. :laughing:
