RE: Saito 115 cam lubrication
Dar, I agree with everything you have said here. I recently acquired my first four stroke model engine, an Enya .46. I have completely disassebled it and noted no abnormal ware on the cam lobes or tappets. There are two holes approximately 3mm in diameter in the dividing wall between the cam box and crankcase. I don't believe the camshaft drive mechanisim receives enough lubrication. I have an idea to circumvent this problem and I'll let everyone know if it works. I just have to decide which of my engines to shoose to serve as a lab rat.
