gum in gas tank

I have been working on a car thats been sitting 40 years The gas tank appears to have been coated at 1 time. I drained the old gas and put a gallon or 2 of fresh gas in the tank and drained it 2 times. I put a clear inline fuel filter on I ran the car with new gas in the tank. The new fuel in the tank turns the in line fuel filter brown. Im afraid that it will clog up the carb. Should I keep running it or should i have it professionally cleaned or maybe someone has a better idea.
