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) = Advanced=20 ignition timing by 2 degrees

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

Maurits
