When running a timing light gun on the pully i see two marks on the edge of the pully. The timing is said to be needed at 10. but when i shoot it there are two marks. when i adjust it should i leave it between 10 like around 15 and 5 so 10 would be in the middle. or should it be 0 and 10?? or is it just all wrong and should only be one mark. but no matter how i adjust the distributor i still see 2 marks. any ideas?
