Do they have drain plugs? You mean to drain fuel from the bowl? If you want to do that remove the 12mm hex below the site glass.

Oh, and if you are gonna work on your junk its best to invest in some FSM’s.

Cheers
 
Thank you all for your input. I was able to drain the old glass from the fuel bowl, hoping that would solve my problem. For background, it has been sitting for several years so I was needing to get all the old gas flushed out. Now that that is done, with draining the fuel bowl being the last step, I was hoping this would solve my problems to get it started. Unfortunately, I can only get it to start for a few second with starter fluid and then it dies. I have drained all the fuel lines from prior old gas and ensured that there are no blockages. I am certain gas is moving from the tank through the filter and pump to the fuel bowl in the carb, however when I press the accelerator, there is no gas pumping into the carb. Any thoughts or suggestions?
 
Accelerator pump is stuck, bad, plugged. Float/needle valve stuck.
Find pinhead's carb rebuild vid. Get a few cans of carb spray and the carb rebuild kit - take it apart, clean and flush all the passages and put it back together.
 
Take the 14mm cap off that sits above the fuel inlet. From there, You can tap on the float needle with a paper clip to make sure gas is getting into the carb.

If the truck will run on the starter fluid, and fuel is getting into the bowl, then it is likely that it is not getting OUT of the bowl, I.e. jets gummed up.
