A quick question re 1991 Tempstar Furnaces.
I notice the blue flames and things are working great but the exhaust duct is rather hot (compared with high-efficiency furnace).
It seems that the heat produced by the flames is not well extracted by the Heat exchangers, a problem with older furnaces.
Question: can one reduce the gas flow at the Honeywell Valve to reduce the flame a bit to be more "fuel" efficient?
Just a "crazy" idea but does this come close to "high-efficiency"?
The idea of high-efficiency is to extract as much heat as possible.

Welcome to HVAC TALK. However this site has rules against giving out technical advice to DIY'ers. I have attached a link below for your convenience.
Here's something to think about though...
When was the last time you had that unit cleaned and inspected?
Fuel costs are skyrocketing.
So why not call in a professional to clean & tune up your furnace? While they are there they can inspect your unit to insure a safe living environment for you and your loved ones. Not to mention, having an efficient running system could save you more than the cost of the service.
What's your safety worth? I'm guessing more than the repair bill. ;)
Thanks for your understanding.

Make sure you install some carbon monoxide alarms in your house, especially if you screw around with the gas valve. you've posted numerous questions pertaining to DIY, and Jultza has provided subtle hints to the rules here. I am certified in commercial A/C but I would still call someone to look at a furnace as I don't have the experience or proper equipment to diagnose them correctly. So pick up the phone,the life you save may be your own.

reducing gas pressure can kill you,

You can't make that into a high efficency furnace by screwing with the gas valve.
But you can have a high eff furnace installed.

screw with your furnace, it will screw you!!!
