The truck sat for 2 years.

Did not realize the fuel tank had a plug on it to drain it.

Does it really?

I will run it down to an 1/8 tank again and drain it out then. Maybe a bunch of gunk will come out.

By the way I have noticed on 3 occasions that the air breather casing around the carb has had some balled up drops of water around in in a few places. The 1st time it was happened was the day I drove the truck home from TN to MI their was a lot of water but after I changed the air filter and cleaned everything up the water has not reappeared except for the few little water drops I mentioned on two or 3 other occasions.

How the hell is that water getting in there? Every thing is sealed up. Could few water drops dropping in the carb or on top of it cause a serious carb issue?

I have never rebuilt a carb like this one. It has a lot of pieces on it. How long does it take to rebuild one and where is the best place to order the kit from? What does the rebuild kit come with?
