Reverse Transcriptase

Can somebody help me? I have started sequencing ribosomal RNA from yeast. I
have used several methods but now, I use the "Promega" protocol published
in "Protocols and applications guide 1991". I have made lot of sequence
gels but in all cases I see only just 120 nucleotides. I changed ddNTP/dNTP
ratio, quantity of AMV RT (2 times more) but it didn't improve situation.
In all my sequence gels I see on the top 4 lines in the same positions
indicating that my reaction always stops. From the literature, I know that
it is perhaps something with my RT. What can I do?

Thanks in advance,
