Timing Chain Jumped?

Paul:
I have to admit that I am not familiar with the Spider engine, but here are
some generic checks that you could make.  They  only apply to why the rotor
is pointing to the wrong plug.  If everything checks ok and the car does not
start there may be electrical or ignition problems.
Check the distributor and see if it is lose.
1.	If it is, turn it so that the rotor points to the post where plug #1
wire is connected.  Make sure that cylinder #1 is at TDC and both valves are
closed.
2.	If it is not, take cap off and turn the engine manually (by hand)
and see if rotor turns.  If it does not, consult a specialist.  If it turns
distributor is working ok go to step 3.
3.	If chain is not broken, line up cam and crank timing marks.
Distributor rotor should point to plug #1.  If the marks can not be lined
up, you have cam timing problem, and probably the timing chain had  jumped.
I know these are very basic and obvious checks, but sometime that's all it
takes to fix what appears to be a major problem.

To John Hertzman:
You are correct that in a two cam engine, both valves can not be open at the
same time.  They share the same cam.  Sorry I goofed.
