1. Im pretty sure the cam is timed correctly. But now you got me questioning it. we lined up the timing dots and the notch cam key. the half circle. im not sure what its called

2. i had a local shop send a stock cam out for a regrind so i think im ok on that.

3. it has compression.

also the gas is stale. i figured it would run not so great but i thought it would still fire.



i really hope i dont have to pull the cam out to check. this is getting a bit tiring

its so damn close to starting. it wants to start. could it be just stale gas?

Check the plugs for wet / fuel fouled. How "strong" is the spartk? Don't discount stupid easy to miss stuff like damaged / dirty cap / rotor or a bad coil wire.

a shot of fresh fuel down the carb throat should make it fire, unless the plugs are already fouled

You can estimate cam timing. Just look at the cam specs. One of the events is close to TDC, EG look them up in the shop manual, EG just picking random, the 318/340/360 specs out of the '72 shop manual, shows the intake valve opens at 10 /22 / 16 degress BTDC. You can EASILY check that, just pull the driver side valve cover, and crank it around. You can easily estimate 20BTC even if the balancer isn't marked, just mentally double the 10* markings

You can also set timing "on the starter." This might be a smart move.
