Thermal switch on thermostat housing for Qjet Carb (1986 K5 Blazer 350)

[ptenhet]

I can't find one of these anywhere and to my knowledge the carb will run rich without it. Is there an after market switch to replace this? I believe it is a 70degree switch to ground. If I can't one, what have people done to get around it?

Thanks

Here is an OEM on Ebay, connection is a stud vs blade connector. This is the same sensor I had on my 84 burb. Not sure what year they changed the Sensor to a 2 wire connection. Hope this helps

Thank you! I ordered one on ebay, but couldn't find much info on it. Do you know what if that one is a 70 degree switch too?

I got that one in the mail and it wasn't the same. Any other alternates?

Does anyone have any info on what the switch does? Does it complete the ground circuit above 70 degrees or does it cut the ground? I have read that if it doesn't work, the carb will run rich.
