ADJUSTING RPM's

[Eagle]

I have fixed the air leak on my DD6V92TA and the RPM's are at 2100 which they should be but I would like to raise the RPM's to about 2300.  There are 3 washers about 1/16 of an inch thick and about 5 that are real thin.  I need an educated guess as to how many of the washers I would need to remove to get it close to 2300 RPM's.

Thanks
