timing help

i have read many articles on how to set the timing on a tpi car and every one i read is extremely confusing on 1 part because they never contain a picture of the timing marker and like most people i cant read the #'s on mine anymore .

so i am asking some one that knows 110% what the markings are to take my crude drawing i made of the marker and label it with the correct #'s where they belong so i am sure once and for all . thanks a bunch , and if a mod sees this please put the pic in the tech article on the home page on how to set the timing .

Re: timing help

Looks ok.

A dial-back timing light is a good investment so you don't need to worry about which mark is which anymore.
