found it on Go2marine. com510 Freak, where did you get that chart from ????
also if the magnet is close within a few degrees couldnt you always tune it out by testing your timing? unless you are WAY off then you shoud be fine if you do the joereeves method of WOT timing your motor because you have no chance of blowing up your motor that way. and if you cant time it then its time for a new flywheel. but i dont think it would hurt to give it a try with just a little time.
