Subject: [LML] Fuel = servo

Hi all,
 
I have a RSA-10 fuel servo on my IO540 that is in a Legacy = and.recently I=20 have done 3 modifications :

1) Added an inlet scoop which = provides 2"=20 more MP at 200knots
2) Turned up the RPM from 2700 to 2850 = RPM
3)=20 Advanced ignition timing by 2 degrees

I now find I can not get = EGT down=20 below 1370 F. I think I am running too
lean. I think it makes sense = to=20 increase the main jet size. Is this
correct? If so, from what dia = to what=20 dia must it increase? If not, what is
the solution?
