Could the “ease start” cams have morphed into “no start” cams?
This is very perplexing, so here’s my “out of the box” theory -
The engine sees higher rotational speed on a push start so the easy start cams no longer reduce compression and the engine starts, alternatively turning over on the starter at c 400 rpm the cams cause the compression to be too low to ignite the mix. There may be a background reduction in compression from another cause that compounds the problem when combined with the easy start cams?
