How to disable electric choke or convert it to manula?

Do not disable it without replacing it with manual.

Unplug it and retune your idle circuit lol

That's it...but you will not have a choke. Converting it to manual? I guess that is possible, but more work and chance for leaks. The 2 stroke chain saw crazies (in U.S) and 4 stroke Honda GX guys here, (Thai) use a simple choke plate. Here is one for a DellOrto...from Treatland's site:
The idea is just to reduce air for cold start. Many ways to do it. This method requires some thinking regarding mounting, as these are at the inlet, sandwiched between two plates. Easy, but not very effective...another place to leak air. Some people put their hand over the air box inlet or cover the filter...not super ideal. Just a pain in the ass. (Too much air in the box). I saw one guy put a plastic bag over his pod filter, exposing just enough for cold start.
You would really be better off buying a proper carbureter that has a manual choke. They simply function better.

These electric chokes are naturally in the Choke On position. The electric power heats a wax motor and drives a pin forward blocking a passage to shut off the excess fuel flow to cause a normal fuel flow condition. Which is what you want. Don't just unplug it and think you're OK.

On typical 4t carbs, the needle is retracted so the enrichment circuit is open allowing extra fuel to the engine. The auto choke (actually auto enricher) unit slowly extends the needle over the course of 45-90 seconds plugging the fuel circuit. After the scooter has been shut down for awhile, it'll slowly retract again for the next cold start.
Unplugging the wires leaves the enricher circuit open continually. Not exactly ideal, but if you know how to start an engine without a choke, it's not an issue. It does help to tune your idle circuit (air fuel mixture screw) slightly richer (half turn ccw) or upjet your pilot one step.
Note, we are not responsible for any issues in using this patch job. It will not fix any issues from a dirty carb or a rough intake system. Use only at your own discretion only after you're sure that your carb is clean, functioning otherwise properly, and otherwise in tune.
Side note, check your float height, float needle valve, and replace your fuel filter first before assuming your choke is at fault. And be sure to clean all the jet passages and other tiny circuit paths as well.

Atariguy you've got operation down except your 180 out on the function. Greginisn is correct. The autochoke is not a choke at all. It is a enricher. Richening the normal circuits will make things worse. Choke reduces air and enricher adds fuel, same general result of making the air/fuel mixture richer for what a cold engine requires.
There are some threads around of people blocking off the enricher ports.
Lots of people talk about how their engine can cold start without choke/enrichment and think they have some sort of miracle of genius mechanicals. What they really have is a engine that's tuned overly rich which allows it to start cold.

Thank you snaker, i had a pretty rough night in the paint shop last night so i'm glad you caught my error! I think i temporarily fried a few brain cells after spraying 20 gallons of carboline paint lol

Atari, you had some of it right.
I removed the enricher, it kept flooding my engine on warm starts. I just run the idle mix a little rich and live with a cold blooded beast on a cold startup. I have to keep the throttle open for 30 seconds or so. The main jets keep the carb running the right ratio at speed. In really cold weather I just open my Vito adjustable jet 1/8 turn.
F*CK the enrichers, I hate automatic functions that only work sometimes.

Nice find. Correct me if I am wrong but I think those are actually manual enrichers and not chokes...right? I know they are calling them chokes but I do not see a butterfly valve and it looks like this will manipulate the same pin that the electric enrichers do. I think I am liking the one for $16. Again, one less thing to screw up and making it hard, or impossible to start or ride once started. I ride in the winter so this would be perfect for me. Thanks so much for posting this, I would not even have thought to look. Bill

Before you buy it look real hard at yours and be sure its for your carb. They are almost universal.

I have seen at least two types of enricher setups, there may be more.
Bill, you are correct those manual conversion kits really aren't a 'choke'.
