1.i always use the bottom timing mark as in the pic for cambelt timing. but i'm thinking that this engine's head may have been skimmed a fair bit, which, when you think about it, will move the cam timing, because you can't actually skim a cambelt to match....
2.cambelts stretch, that doesn't look like a new one...
3. have you tried moving the cam pulley one tooth forward to see if it runs any better?
It would have to be skimmed a massive amount to affect timing that much!??
stranger things have been done to an engine before.... it might have been skimmed 6 or 8 times in its life.......or once badly.
I seriously doubt it,theres only so much you can take off them.
You will be saying someones skimmed the cam box to increase valve lift next......
yes your right with regards to spark timing
what needs to be done/checked is the timing between the crank and the cam.
i just took some pics but my phone cable is at home so i will post up later
unless someone can post some up earlier
nicked of migweb
notice the pointer on the pulley above this needs to line up with the notch/mark/cutout whatevers on your engine see the little cutout just below the pointer?
the cam pulley below lines up with the notch on the back cover, its a painted mark on yours so line up with that assuming the back cover has not moved as you said earlier
this is the physical engine timing, now fit the belt
one this is done turn the engine over a few time by hand to check that the marks end up in the same place.
now replace the altinator pulley and start the engine, check spark timing with your strobe light and adjust with the dizzy
hope this helps mate

this engine is so old, i don't think it has the bottom marker arrow like the later ones.
i've been ridiculing that particular myth for longer than i've had my views on head skimmingOriginally Posted by Andy
