i have a 69 camaro 305 built engine that i am having problems with. i can set the timing but when reving up the engine the timing does not change any. vaccum advance also does not change anything. the car runs strong when timing set at 30btc at 2500rpm but is hard to start when hot. if i lower timing starts ok but runs poor. what do look i look for. why does the timing not change.
if i set it at 2500 rpm then drop back to 1000rpm there is no change. i can run it up to 3500 rpm and still no chang. any ideas.
the center plate under with the springs would not turn at all. i was able to get the center plate off, but it fits down on the teeth of the shaft. is this correct? should it fit this far down. how does it turn. i cleaned and oiled but did not correct anything. the bushing in the center plate looks like someone had maybe driven it down on the teeth of the shaft. should i buy new center plate and try that
