Sounds like the timing is to far advanced.

first you need to time up the cam the vernier will not be set in the correct postion then you need to set timing with the distributor
depending what cam you have in between 12 to 16 degrees on the distributor
cam timing as per makers instructions

Start again
Have you fitted a new cam shaft ? ie 285 piper
If so you will have to time the cam in first
This is where the vernier pulley comes in .
If its a standard cam [ ford ] you can set the timing by putting the old pulley back on set it all up lock the cam and crank then slip the vernier
pulley back on
You may have to remove the dizzy and re time that after setting the cam up

irrelevant - vernier doesn't need to have marks.
firstly you need to time the cam - this is important as if you have this wrong, you can get pistons smacking into the valves whicih is not ideal.
get a timing disc - nothing more fancy than a protractor showing 1 degree increments - you can make this yourself - I have one that can scan and
e-mail to you; then cut out and stick onto carboard. Or you can buy one.
Then read this:

This explains it better than me plus I am not gonna sit here for the next 10 minutes writing it up!!
Make sure you understand it - it gets confusing since all timing is in crank degrees yet the crank to cam ratio is 2 to 1 (2 crank revolutions to one
cam revolution since 4 stroke engine).
Depending on your cam, the inlet full lift degrees will be around 103 to 108 degrees.
Choose any one of these, or a value in between - it won't be ideal, you may loose a couple of percent at most but your engine will run.

here is a crossflow being timed - not the best picture but you can see the dial gauge measuring inlet valve 1 lift and the timing disc and wire
pointer.
