Setting the camshaft timing

[Andyb]

Hi. I am trying to set the timing /camshaft timing marks. 

I have set the timing mark to the 'T' mark, however I can't get the exhaust mark @ 2 to be vertical. It's leaning slightly left. Is getting the 20 links pins between exhaust 2 and inlet 3 mark more important than the arrow being vertical?  

Sorry it's a bit of a weird question, but I assume having this out of sync will end up with bent valves and hard to set  

TIA

Unless it can be corrected by moving it one tooth on the chain - its the wear & manufacturing tolerances stacking up. Its usually the horizontal ones along the head face I used?

Cheers @Gixer1460. Moved across a tooth and alls good at the moment. Just the joy of putting the carbs back with the air box. Ta
