How did you know that your valves wer in the right position corresponding to the position of the tdc on the rotor??is it due to cam lobe positioning do thay just sit in the right position open or closed???Surely you need to now what position they are in,you cant just chuck the cam sprocket on hoping that are right???or csn your lol,please help I'm just doing a rebuild on this motor cheers
The cam is set with both lobes facing down away from rocker pads . This point on the camshaft is called base circle it is when both valves are closed and the engine can fire . This is for any 4 stroke engine . It is also the point where you make your valve adj. . At this point your piston should be at top dead center with both lobes facing down now install the cam gear to the timing marks lined up . In some cases you may find the mark 1/2 tooth ahead or 1/2 tooth behind sorry but I can't fix that . Someone else may know . I have not tried moving the chain on the crank that may or may not help .
you will know it when your cam can rotate back and forth easily. if your cam is in a "binded" position (with both valves closed), it means you have to rotate the cam until it frees up. when you install the gear, your camshaft should rotate freely, the amount of degree depends on the cam. use needlenose to rotate cam until u find the position where both base circles are swinging freely (as explained by 2x4 barrel).
A would worry more about the hole at the bottom of that sprocket and where that oil is obviously funneling out the bottom holy crap? Obviously it’s just a timing video!😂
Just the information I was needing. Thanks and GOD BLESS YOU
Thanks for the video it really helped me out mate 👍

Gonna replace my piston rings tomorrow hopefully this works?
Thanks mate :)
Thanks
saved me some head ache...
What happens if your timing is bad?
You will either have backfiring and a badly running engine or if its too far out it will bend or break a valve

cough and fart hahaha ah
