Hot Start Issue Choke stuck?

The advance specs will look like this. Here's the section from a '69 FSM from posted by stumblinghorse. '74 is probably different. The only question is how much different.
To figure advance on the engine.
1.5* @ 550 rpm = 3* @ 1100 rpm crankshaft speed. minimum
6.5* @ 550 rpm = 13* @ 1100 engine rpm. maximum
So we can see there is a pretty big increase in timing from the initial to 1100 rpm, as much as 13*.
The rpm of the initial timing is in the Fuel section of the '69 FSM, but generally its around 650 - 700 rpm.
By '75, it was also on a sticker someplace in the engine compartment. So you may find it there in your '74.
When dealing with a factory CAS setup that uses retarded initial timing, especially with hacked up emissions systems, I would experiment with more initial, at least to get it running.
The non-CAS 318 provides some guidance for a what more normal timing and advance would be. Starting around 5* BTC at maybe 700 rpm, it would then advance 1* to 7* by 1000 rpm. This means the timing at 1000 rpm would be 6 to 12*.
Use this to estimate if the timing is in acceptable range when you can't get the engine speed slow enough to establish initial.
The reason to keep checking the timing at different rpms is we don't know if the distributor is the original one.
