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::cool: 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?

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::rolleyes:
