Craftsman tiller won't run

My neighbor brought me his Craftsman tiller that is 8 years old and had been used twice since new. It hasn't been used in 3 years. Of course it still had the gas in it which had turned a nice shade of brown. It did start up to my surprise. As long as I kept the choke on, it ran pretty good. I decided to pull the carb and give it a good soaking and ran wire through the passages. Put it back on and not much better. It was nasty inside. Decided not to fight it and bought a new correct number matching carburetor. Put it on today and it is surging like crazy if I try to run it without the choke. It does have new gas in it, a new plug and clean filter. Gas flows freely to the carb from the tank. Am I missing something? Or do I just need to adjust the new carburetor? It starts right up as long as choke is on. If I try to move the choke off, it dies very quick.

Thank you

Surging still points to the carb. I don't think that carb has any adjustments that will affect it.

Why would a brand new carburetor do that?

Is the new carb. a Briggs part or an aftermarket brand? I have seen a number of Chinese made aftermarket carbs. that are bad.

There could have been some remaining crud in the fuel line when you added the fresh gas, fresh from the pump, not fresh from a can that has been setting since last year. The bowl nut is the main jet and may have gotten clogged, refer to the pic below, also spray some brakeparts/carb cleaner behind the carb while it is running, if the engine tempo changes you have an air leak. Have a good one. Geo
