I'm learning about how to build engines 1 component at a time and my latest question is about cam choice. I'm allowed a cl2 (from dyno cams) but I see different styles- retard timing, minus lift, & normal.
I would assume minus lift would just mean the lobes aren't as tall but the timing would be the same as the normal. Would this be for a higher rpm engine? What's the purpose of minus lift?
For the 2 degree retarded timing cam, when would that be used? I understand advancing timing with a flywheel will create a spark at a different time so the combustion can be harnessed better. Would retarding the cam timing basically be the same as advancing the spark timing or am I thinking about this wrong?
Thanks for the help, I will be building my 7 year old her first clone engine during winter break and just want to understand why certain parts are choosen
