hello everyone, this is my first post i hope i can enplane my questions clearly.
i took apart my Hyper .21 8P after engine was seized for not being in use for years,
i free it and removed fuel residue with WD40, and it's nice & clean now and not sized enymore.
question is
when i put back the header i noticed a black round spot marking on the surface of the header ribs (like in pic)
but did not know which way to align it, at this moment Ive placed it overlapping engine sleeve markings, i.e front,
but is that correct ?
what the mark looks like:
tomorrow i will try run it, after years of dust collecting, and i wanted to have some confident
it's plugged correctly.
