Amazingly helpful! I appreciate your skill and time making videos like this. I was searching for instruction on this crazy Toro auto choke system as I have a mower that starts and almost immediately dies. I figured it was thermostat control or diaphragm but wasn't sure how to test. Your excellent video provides exactly the right detail for me to continue troubleshooting this issue. Many thanks!
I just bought a new Husqvarna push lawn mower (L421P) with a Kohler HD775 engine; I'm sure it has this autochoke system. Can you give me a ballpark figure on how many hours before the autochoke fails? Will reputable repair shops install a manual choke system in place of this? Thank you.
I could not give you an educated guess on the life expectancy of any mechanical part or system but I do believe longevity is always based on proper maintenance of said parts and systems. I can say that I always prefer a manual choke system, or even better a primer system due to the simplicity of those systems. A lot of autochoke systems require over-engineering to work. This complexity (extra parts and gadgets) creates their own issues in the long run. As far as converting over to a manual choke system, there is no produced conversion kit that I'm aware of. So, any switch over will be a "backyard" fix which you can never really guarantee it's life expectancy either. Since most OEMs are all switching over to autochoke type systems for "user simplicity", I believe these systems are here to stay.
I didn't leave it run long enough for it to fully open. I knew the bimetallic spring part worked. It was the vacuum actuator that wasn't working. Also, the vacuum actuator will not fully open the choke flap on it's own when it first starts. Just enough to have it run properly until the bimetallic spring opens it the rest of the way. Thanks for watching. Cheers

@@brantsmallenginerepairs I appreciate your answer; thank you.
What is the part # for the diaphragm, can't find it on Kohler parts breakdown. This seems like a vary common problem. Thanks for the video.
Pretty sure this is it.

@@brantsmallenginerepairs I'll check to make sure, I couldn't fine it . "Your right", It is 14 268 04-S Thank You
Hey I didn’t really see it open all the way on last run
I didn't leave it run long enough for it to fully open. I knew the bimetallic spring part worked. It was the vacuum actuator that wasn't working.
