First look for any hoses that are off and then spray the old "break clean" around the carb.
If the rpm's go up you found the leak.
It sounds to me like you might have a timing issue also.

Man, you have good hearing!!

Actually speaking of a timing issue, my wife seems to think I have one of those as well.

If you press your ear really close to the screen you can hear it too.
See what I mean.
