Q:

20 hp Twin 460777-1297-01 Briggs&stratton Briggs and stratton engine

A:

Thank for the inquiry and for using SearsPartsDirect.com.

The Briggs engine 461707-0145-E3 was manufactured in 1999. I was not able to make sense of the Briggs engine 460777-2271-E1. The type of 2271 is what my database didn't recognize. The closest result was 460777-1297-01, which was manufactured in 1997.

I went to the Briggs site and they group the engines based upon the series of 420000 or 460000. The two you have mentioned would fall within the 460000 series. I can mention that the type of 2271 or 0145 would tie back to thier application, like a tractor or generator, the type of design to fit that application like horizontal or vertical shaft, and the brand they belong to like Craftsman or Cub Cadet. The last numbers E-1 and E-3 go back to emmission purposes, which isn't too critical. 

As long as the mounting for the two engines are the same, I would see no issue with the swap. They both fall within the 460000 Briggs series, I would suspect they just come from different brands of tractors, which is why I couldn't recognize the 2271 type from the 777.

For your convenience, I have provided you a link below that you can click on to be directed to the Briggs & Stratton website where you can download and view the manual for the 460000 engines.

Q:

Engine cranks but floods out 917270940 Craftsman Tractor

A:

Thanks for the inquiry and for using SearsPartsDirect.com.
Sorry to hear of the issue you're having with the engine flooding when trying to start it up. I know how frustrating that is to have occur.
This sounds like a carburetor issue, but I'm not entirely sure what you mean by "pumps fuel back out carburetor." Most of the time for flooding related issues, the float inside the carb is stuck in a down position from the needle sticking into the seat because of varnish and debris. 
The first thing I would do is pull the carb, and inspect the needle and seat. I would also recommend checking the float to see if it has a pin hole and is fuel logged, which would also cause it to not regulate fuel properly. That is more than likely where the issue stems from.
While the carb is pulled, perform a thorough cleaning of the entire inside inside including the main fuel jet. Have a full can of carb cleaner, a wire brush, and a bread tie wire or a small gauge bailing wire to clean the jet. If you miss any of the varnish on the first cleaning, you will more than likely have to open it back up to clean it again because the old varnish will dislodge and block the jet or restrict needle movement again. 
On a side note, anytime you experience flooding issues, you will want to check the oil and make sure fuel has not mixed with the oil. What happens with flooding is that the excess fuel migrates past the cylinder into the oil sump. It mixes with the oil and thins it out. If the engine is running with the thinned mixture, it can cause internal issues. Once you correct the flooding, I would recommend performing an oil change irregardless of whether you smell fuel or not. 
Hope this helps, and thanks for using SearsPartsDirect.com. We appreciate your business.
