Oh, its very simple, if you have 34* of timing at idle, and you're idle is set below 2,700 RPM or so, which I expect for that cam is probably around 900 RPM. Then it would be detonating a LOT from take off- that's kind of the whole idea behind having mechanical advance on a dizzy- so you have more timing when you need it, but not too much when you are carrying a high load at low engine speeds.

to simplify it 34* timing + that cam + that compression (at take-off)= BOOM!
