If you are getting two out of the three sats, you skew should be very close. Once you cover the outer lnb's, remove the coax and run a check switch to clear the matrix. Recconnect the coax then rotate the dish to your left as you stand behind it and lower the el till 119 comes in. Fine tune the signal level for 119 verifying signal strength on several different transponders, remove the foil from one of the outer lnb's (you may want to do 129 since signal strength is usually a little lower). Fine tune for a few of those and keep checking back with 119 to make sure you are not losing it, it may go down a couple of points as long as it is not too many you should be good. Then see where you stand on 110. Keep in mind, depending on the type of lnb and switch, you may be only seeing high 50's. Don't frustrate yourself trying to get 125 because you are never going to get that high (the meter is not a percentage and the software changed over the years and you are not going to get anywhere near that level). When 110 and 119 are close to the same and 129 is only a few points lower, then tighten all the nuts and bolts so the dish is as secure as it can be (don't break them), then run check switch to verify all sats and you should be done.
