What does 'cleaned the carb' mean to you?

 

Reaming the jets is not 'cleaning the carb'....you probably pushed debris into the passage above the pilot jet...

 

Where is your fuel screw set?

 

Did you check the hot start, and cable nut for leaks?

 

 

Does it idle?

Dropped the bowl and removed the jets. Soaked them in mystery oil for a bit then blew compressed air through everthing. Fuel screw 1 1/2 turns back from closed. Have not checked the hot start and cable nut yet.

Blowing compressed air from the bottom up guarantees you blow any loose debris up into the narrower carb passages...

 

You probably have partially clogged the pilot jet passage and the fuel screw passage

Ream them with #15 fishing line and REPLACE your pilot jet with a brand new one

These pipes will glow red at idle, but I never seen one that red.  That can not be good for the motor.......
