  We explore the possible association between the microquasar LSI+61 303 and
the EGRET source 2CG 135+01/3EG J0241$+$6103 by studying, with a detailed
numerical model, whether this system can produce the emission and the
variability detected by EGRET ($>$100 MeV) through inverse Compton (IC)
scattering. Our numerical approach considers a population of relativistic
electrons entrained in a cylindrical inhomogeneous jet, interacting with both
the radiation and the magnetic fields, taking into account the Thomson and
Klein-Nishina regimes of interaction. Our results reproduce the observed
spectral characteristics and variability at $\gamma$-rays, thus strengthening
the identification of LSI+61 303 as a high-energy $\gamma$-ray source.
