Anyway, long story short. I redrilled a extra cam gear I had to advance the intake 2.5 degrees.
I am positive I drilled it correctly. I have access to a machine shop and high accuracy measuring machines.
I marked the timing chain and redrilled gear. Swapped the gears out directly, having to move the intake cam slightly because of the new redrilled cam gear.
Rotated the engine by hand and it felt okay. Fired it up and it idled poorly and make loud clicking noise. valve hitting pistons? oh no.
So, I looked around at pics of other cam swaps, looked at mine and thought that mine did not look quite right. Intake cam was at 10 o clock position while the exhaust was at 3 o clock. So I rotated the intake counter clockwise 1 tooth. Rotated the engine by hand, felt good so I fired it up. It runs pretty good, but I am not convinced it it right.
I don't know why I had to go the extra tooth. I am sure I marked stuff up correctly, but I obviously screwed something up.
So I took some pics for you guys to look at.
Do they look correct to you? It is at exactly top dead centre. I know pics are not easy to tell but please let me know what you think.
I still need to get this thing smogged.
