Hello All !
Steve I abandoned the line trimmer carbs. for .8 RC carbs, they work well and are cheap enough for me. I find used motor oil (not syn blend) , alcohol and 50% water works good enough to cut the grass. Please do check in on the yahoo group vortexheatexchanger, one of the dealers has a diesel subaru running with 50% increase. The moderator also has his diesel vehicle running on the geet system of Paul Pantone. Also take note: the inventor has also joined the group.
