To run, an engine needs fuel, air, compression, and spark - in the right
amounts at the right time. Being 95% sure of timing throws up a lot of
flags - you must be 100% sure or the statement means nothing.
1. Check the compression. - if has good compression on all cylinders,
assume the cam is installed correctly and that the valve lash is
adjusted enough to start the car. If not, find out why and fix it.
2. If has good compression on all cylinders, rotate engine to TDC#1 (#1
valves will both be closed and timing mark will be lined up) and check
to see that the distributor rotor is pointing to #1 plug wire and that
the points are just about to open. If not, find out why and fix it.
Also check to make sure the firing order is right.
3. If it still won't start, crank the engine and watch the points - you
should see an arc as they open and close. If that is OK, hold a
screwdriver that is grounded to the engine with a wire in the vicinity
of the coil center terminal while cranking. A spark should jump to the
screwdriver. If OK, use an extra spark plug (grounded to the engine) to
check the output of each plug wire while cranking. If problems are
found, fix them.
4. If no problems are found in 1-4, then verify fuel quality and finally
carburetion.
