cam timing
i am in the process of building my engine as it was in bits previously i just need to check i have set the timimg correctly:-
the line with the t mark next to it on the flywheel is in line with the crankcase joint at the front of the engine,the camshaft dots line up with the little dots on the camcaps and the camshafts face away from each other while no1 piston is at top dead centre.my question is do i have to set any ignition timing or does it know when the camshafts are facing away or towards themselves for starting purposes
cheers mike

Re: cam timing
The holes on the cams line with the spots on the cam caps. The spots are on the right hand side of the engine with the exhausts faceting you.
The flywheel only fits on in one place and the woodruff key locates it. The timing is taken off the flywheel.
Turn the engine over by hand, if it stops don't force it

Re: cam timing
when you say the holes do you mean the ones on the outside face or the ones on the edge(look like centre punch marks)these are the ones i have used and it turns over fine

Re: cam timing
Yes the center punch marks.
Sounds like it's good to go.

Re: cam timing
You think that was difficult?
Try it on a 12 cylinder Volvo Penta industrial engine after a rebuild (there's four heads for a start!). I did one this week at work and it took ages 


Conventional wisdom says to know your limits. To know your limits you need to find them first. Finding your limits generally involves getting in over your head and hoping you live long enough to benefit from the experience. That's the fun part.
