Outdoor Power Equipment and Small Engines - How to clean main fuel tube on b&S carb

I have a 5 hp B&S engine. It is a model 130202 type 2915-01. I think the carb is from a 130292 as it has a choke on it as opposed to the welch plug. The carb etc was all gummed up. I removed the carb and sprayed it with carb cleaner then lightly cleaned the screens on the fuel tubes. For some reason this one has two -- a long and a short. I blew air through all the passages I could see. I replaced the diaphragm in the fuel pump and replaced the carb to tank gasket. I cannot get it to start without priming it with starter fluid. I think the main fuel tube is clogged however I dont know how to remove it to clean it. It is plastic of some kind. The screen at the end of it looks fine. Also is there a jet somewhere I am missing.

I recommend soaking the carb in a bath type carb cleaner. Those carbs can be difficult to clean when they get bad.

After cleaning these carbs, it is difficult to get them to prime, manual recommends FILLING gas tank. Try this but you may have to replace pick up tubes, short one is easy long one a little more of a PIA. As Cheese said soaking is best way to clean
