Re: TD 366 timing
need to do a little work on a sheet of paper, find out how much advance your vacuum can is worth if its not adjustable. i would find out what a bbc likes in total advance at cruise.
initial+vacuum+mechanical....on a sbc they tend to not like anymore than 50-52.

Re: TD 366 timing
I set the initial at 8* it has a carter 650 AFB on it the newer style and now it seems to have a pretty large stumble in it on take off at idle and part throttle smashing of the peddle i dont have a vacuum gauge to set the idle mixture screws but they should not cause the part throttle bog or stumble right? is there any other way to set them
BTW i run 87 octane gas and some times a little bit of 93 |
