Well, its been a while since ive discussed carb's, joy! I dont have any 
info on the carb you have, but I suspect that it may have a second 
small fuel filter at or near the carbs fuel line inlet? It sounds like 
when you disconnect the fuel line its allowing enough backwash to clean 
out the line, until you again have the blockage. I know that sounds far 
fetched but its the best one I've got for you at the moment. I tell you 
what! Send me an airline ticket and I'll come have a look-see! (First 
class seating for 2 would be suficient. <G>)
 
By chance did you cut open the old fuel filter to see how badly clogged 
it may have been? Im wondering if your fuel tank is corroding and 
starting to flow particles to the carb.
Do you have an electric or manual fuel pump? Its just unusual for me to 
hear of a carb on an 87! Was this factory fitment or an option for you?
