16v locking flywheel

[golfmk4owner]

Guys im timing my KR 16v gti, everytime i tension the belt the flywheel mark moves out a few degrees. How bad would this be? If its bad, how do i lock my flywheel i cant see and holes
Cheers. Sorry if its somewhere else, difficult to search im cocvered in oil

i've never had to lock the flywheel,  just pull the belt tight ish to the cam then pull the cams forward a littel  with a spanner so the teeth line up then when the tenstion is taken up the timeing marks should be spot on
