First: If you can buy a SuperDish 121 and a receiver for $50 that are working - buy it, especially if they are throwing in a DP34 or DPP44 switch.
....SuperDish 105 or 121 with DP34 switch -- About $190.00 plus shipping.
....DPP44 switch -- About $190.00.
Someone on the forum is looking for the LNBF cluster for a SD 121.
Second: As others have said, you really need the mast plumb before starting. However, if the bubble is on the line, it should still be easy to find a speck in space. Although that meter may get you in the right spot on the sky, you will still need to move the dish about 1/32" at a time to try and find the bird. The receivers do not respond real quick. Also, is that meter compensating for the yearly magnetic deviation for your location?
Third: I just looked at the pictures. I don't think your settings are correct, unless the pole, dish and receiver were bought from a neighbor and you just moved it without adjusting anything to pick up the same satellite.
If you respond back with your zip code, I'll compute your settings for both 148 and 61.5, based on the following equipment:
