I want to know any ideas to make an auto choke for my home generator. I have an automatic transfer switch (ATS) installed which turns on/off the generator.

Most of the time, it is not necessary to pull the choke, the generator starts anyway.

In cold weather, it causes problems during starting. The ATS tries to start the generator, and after 4 tries when the generator does not start and there is no feed to the ATS, the ATS goes into error mode.

The J shaped choke needs to be pulled and then push it back

The J shaped choke needs to be pulled and then pushed back during starting.

I just need to know how to pull and then push this, using some kind of solenoid or something, then I can automate it using Arduino or any other microcontroller.

I want to know if there is any cheap and easy way to make this manual choke work automatically?

  • \$\begingroup\$ Or you could copy the essential parts of an automatic choke used on motor vehicle carburetors: A bimetal spring that always holds the choke plate closed at room temperature. And a passageway for exhaust heat to warm up the bimetal to open the choke. Since your throttle is governed or otherwise controlled, there is no need for a fast idle cam or kickdown lever. \$\endgroup\$ – John Canon Jan 9 at 6:48
  • \$\begingroup\$ Measure the distance the J needs to move, or check out ehat it actually moves and consider moving that. Then find an actuator, 12v possibly and control it. \$\endgroup\$ – Solar Mike Jan 9 at 8:24
  • \$\begingroup\$ @SolarMike As I'm looking for the cheapest solution, a normal Actuator is $36.06 in Pakistan, while a DC 12V solenoid with 10mm stroke and 42N force costs only $8. I feel that 42N is enough to Push and Pull the J. I'm gonna buy this one and try it if it works for me, if not then I'll consider an actuator. \$\endgroup\$ – Khaalidi Jan 10 at 6:05
