I found the post where a guy bored out the intake manifold. The carbs on his motor and the 25hp had different part numbers but all the individual parts for the two carbs had the same part numbers just like mine. I decided to bore out the hole in the manifold to match the carb. I took it up to the lake today for about an hour. This motor has sputtered when I run it at a certain speed since I got it about 5 years ago. It is like it misfires about every 15 seconds. Now it doesn't. I could not get it to do it once. Also this motor has never idled in neutral let alone in forward gear. Now it does. I didn't not check the speed of the motor before I did this so I have no idea if it is any faster.
