How Does an Engine Choke Work?

Have you ever set the choke on a mower or chainsaw and wondered exactly why you need to do that every time you start it? I have...

And it's been this long before I actually took one apart to find out what's inside.

That helped me to understand the choke. Your explanation was very clear. Thanks.

I appreciate you taking the time to explain the concept of a how a choke operates! Great video! Very thorough explanation. 👍

This helps a lot! I always have trouble remembering which way the choke is supposed to start out when I'm trying to start a cold motor, so I'm sure it'll help that I now know a little bit about what it's actually doing.

Understanding that the choke is “choking” off air and not fuel make so much sense now. thank you for this explaination!!!

[WheresNaldo]

Best video I have found that explains choke function. Thank you!

Appreciate your time putting this video together and explaining this simple feature so well. Fixing up a generator now and this helps so much.

Your manner of explanation is extremely clear and easy to understand. Thank you!

I wondered the exact thing you mentioned in the description, but I wonder no more because of this video. Thank you very much.

Fantastic info. I didn't know which was the choke position, where I pull and hold or when it snaps back when I let go. The pull closes the choke - release opens it for normal operation. To many this is obvious but not to me so this was a big help.

[martybell]

Just to reiterate what others have said... Exceptionally well explained.

[HeavensWaiting]

I came with a question and left with a clear understanding. Thank you.

This was awesome, thank you! I’ve stranded myself one too many times while out boating. Went far out and had to get towed back. I now know I was flooding my engine. I would smell & see fuel oozing out of my engine onto the top of the water.

[corylowe]

Wonderful explanation! Thanks for making this.

[fairplayer]

Dude thank you. I actually understand the principles of the choke now

[Just_some_guy_who_loves_God]

That was soooo much better then all else that I watch. I feel like I actually understand now.
