I recently swapped my 17 hp (seized) briggs twin with an 18.5 hp briggs twin. These are not the V twins put the old style motor with opposing cylinders.
The motors and carbs look identical.
Question can I use the carb from the 17 hp on the 18.5?? They do look the same but am concerned that the the jets may be slightly different.
Any help would be appreciated.

Will need the model, type and code from both engines so I can look up the jets for both engines.
