Tim,
Yes, I did clean the screen.
I just went outside and again the truck started right up. I did notice that
there was as layer of ice beginning to form around the base of the carb
after Buddy had run for a few minutes. So more and more, I think that the
problem could be the stuck heat riser. Yes, I think that there is fuel in
the carb after a night's rest, but I'll check tomorrow to be sure.
So you know the conditions here this morning, it's about 40 degrees here in
Austin. What's it like in Ft. W?
