Hi Deejay,
thanks for your time.
Unfortunately I'm already a member of the manual area but I couldn't find any usefull info. In the lawn mowers parts and manuals area there are only manuals of vintage engines(or maybe I'm looking in the wrong section..).
I'm pretty sure the poppet valve should be on "C" also in a VSX engine, but I'd like to be 100% sure.
Cheers.
