I tried to blow out any obstructions (spider webs) in the burner tube
with compressed air.

I replaced the thermocouple. Pilot light works fine.

The burner flame still looks like it isn't a full flame.

What is the best way to clean the orifice ???

Thermostat works fine.
Burner may have low flame.
Blower takes about 5 minutes to come on.
Forced air out of ducts is not as warm as it used to be.
What is the problem with slow & low heat ???
