[Adjustable Timing Plate]

Is someone know the bolt size for the pick up coil because I will need 2! When I try to unscrew the pickup coil from the oem plate I stripped the bolt and need to know the size and thread and length of the bolt?

[Rebuilt question]

I have buy a alloyboltz complete stainless steel bolt kit and wonder if anyone use the bolt instead of the stud for closing de case? 

I have a CPI SERVAL 421 and want to know how much timing advanced I need with pump gas(cool head 24cc dome)? 

I have a trail tech vapor and want to kkow the best method to have an accurate RPM?

Probably already answer somewhere else but I can't find it... Is something can be done to make the stator more reliable? From what I read stator are know to gone bad! 

Thank you for your time
