225 Dart chugging past 70...

Get ready to laugh at my expense. It's time to remember to keep it simple...the plastic fuel filter before the carb was plugged. Granted, it had to reach that state somehow, and that somehow was likely running the tank dry because my gas gauge doesn't work. For now, however, it will exceed the legal speed limit with no bucking bronco impersonations. Thank you all for your help. There are no guarantees I won't have to drop the tank anyway, but it's working for now. :)
