I while back I bought a used plane out of a consignment that has a Saito 65 on it. The engine seems to be old but in great condition and fires up easily. The high end is easy to set but the low end is a mystery. The other club members that have helped me with it are not familiar with the carb on it. It appears to have an air-bleed low end adjustment that I can't find any information on for this particular engine, the only 65 documents I have seen show a low-end adjustment via a screw inside the end of the throttle arm.
Could someone verify this from the attached pictures taken either side of the carb and give me some advice on setting the low end. I think I have it set but after flying for a few minutes if I try a touch and go I invariably get a dead stick..
