Carb bolted on and motor fired right up as expected, except... 2 things. 1..You will need:Pn. 25 158 08-s (or maybe 25 158 11-s might also fit/work, but I forgot to try it) bushing for the throttle linkage to fit the throttle shaft plate. It has a big hole in it, and linkage work work until/unless a bushing is also installed - NOT included with the carb. 2.. You will likely need to adjust the IDLE mix jet - side of the carb, recessed screw above the float bowl, closest to the mounting flange. Once this is adjusted, motor idled just fine. I came out about 2 turns I think it was.
