I've been off the list for the past couple of years as the Triumphs
went on hold in favor of other pursuits, but now I'm reassembling the
1969 Spitfire I disassembled some four years ago.
I have most of the engine back together, but my question is about the
camshaft timing.
The Haynes book says "It's easy to get the camshaft 180 degrees off".
According to my calculations, the camshaft turns once for each two
revolutions of the crank. So if the cam sprocket is 180 degrees off,
doesn't that simply mean that the next revolution of the crank is TDC
on the compression stroke?
Once the timing gears are covered, no one can see where the timing
mark on the cam sprocket is anyway, and we always find TDC on the
compression stroke by observing the behavior of the valves, so if the
timing mark on the cam sprocket is 180 off, how can it matter?
I'll bet I'm missing something here...
Anyway, I want to make SURE I have the timing stuff right before I go
on...
Thanks!
