Thermoquad low vacuum readings

Hmm. i dont know if that is defeating anything related to your issue. Does it not work or is it not propped open during hot idle? OK, just read your post. If the TQ requires a rod to the OEM choke mechanism to apply, then it should not require a strap to keep it open, just a lack of 'pull' from a divorced choke. I dont have one on the wall anymore so I cant tell if the choke is sprung on carb. TQ guys: does the divorced choke push/prop the choke open when hot? If so, then wire that rod up.
