RC Extreme power. That was a very good video on how to set timing at a preferred setting. Thanks for taking all the time to do the video also. I am going to make a similar video on a timing ring made of aluminum with the magnet in ring. The ring has a set screw and all you have to do to vary /set timing is loosen the set screw and rotate the ring a tad. It will have reference marks so you can see advance or retard from a sweet spot. Capt,n P.S. I have already done it on a engine and it works perfect.
