Malcom Stride plans/article indicates in figure 4 the cam timing diagrams as Clockwise, furthermore it specify the view from the timing belt side.
The engine turns CCW when looked from the propeller (timing belt) end, the side one would face when phasing the camshaft.
The picture of the two cams in figure 4 must rotate CCW if we want to have the long arc for Compression and Power Strokes between Inlet and Exhaust. The short 105 degree arc between Exhaust and Inlet must be traveled from Exhaust to Inlet implying a CCW rotation of the Cams.
I initially assembled the engine without even looking at the article and timed the camshaft by eyeballing, the engine runs great but I am confused now.
I am reassembling the engine after the initial test run and refer to the article fro "proper" timing.
What is the problem?
Article Error?
