hey guys how are you ihave a dt 175e i was just trying to find out how to redard the timeing to spec 1.8mmBTDC i under stand how to line the piston i can do that easyly i plan to use a flat piece of steel across the bore with the head removed and a feeler gauge, but what els is involved? when i did the crank seal on the left i lined the magneto base plate up with the two line marks on the uper right hand side and thought nothing more of it until i came across some thing i read in a forum recently, spinning the base plate is this how you alter the timeing if so is it just a case of lineing up the piston to spec then alinging the base plate up with the markers am i on the right track or not any help is allways apreciated thanks guys bye

Hi Shaun, quite an ingenious method of fixing the ignition poin there

You are right about your assumptions too, see if the picture helps
