My son’s Animal Cadet is 2/3rds of the way through the first season and I am looking at the ignition for the first time. I read some posts about the air gap being set to 0.016 on the outer legs. That is noted on his green PVL coil also as in the pics. However, the coil has 4 legs and in my case only 1 of the inner legs was set at 0.016. I also notice witness marks on the flywheel indicating the legs were dragging or some dirt got in between the legs and the flywheel.
Is there any spec for the 2 inner legs? I have read some of the posts debating wider air gaps, I just want to set a baseline at stock. Can someone please have a look at the pics below and let me know if it is indeed #1 and #4 in my pic that are the legs to set to 0.016 or a touch wider? What about the inner legs #2 and #3 labelled in yellow in the first pic?
Also I noticed 2 polished marks on the flywheel at is close to but to me doesnt seem exactly TDC in relation to the coil. Is that correct? Is there a stock mark and arrow for TDC or do I need to put a dial indicator onto the piston through the plug hole?
