I've run the needle in all the way and things don't get any better, so I emailed Joe at Revmaster and he suggested a heat box for the carb to warm the fuel as it enters the intake. Now I'm sure he is not talking about using carb heat as I have that, ( is there some elec device )plus that would be ineffective for 10 min or so till the motor warms up.

There's not much heat available initially, so that seems like bad advice. I've run carbureted engines at -20 with nothing like that. Did Joe say warm the fuel, or warm the air?? Sounds really hokey!!!

In cold weather below 50 deg or so the thing runs so rich that it fouls the plugs so bad that I need to give up for a couple hrs or so. I've run the needle in all the way and things don't get any better, so I emailed Joe at Revmaster and he suggested a heat box for the carb to warm the fuel as it enters the intake. Now I'm sure he is not talking about using carb heat as I have that, ( is there some elec device )plus that would be ineffective for 10 min or so till the motor warms up. Anybody know what Joe was referring to?? Joe seemed to think that due to the lower temps the fuel was not vaporizing properly.

I 1999 at the Kentucky Gathering, I weighed in at 256. I went on Atkins 6 months ago and I have lost 38 pounds so far. my goal is 200 so I only have 18 to go. But then, I would really like to get down around 190. You can do it.
