Jester, I do not know what ignition you are trying to adjust the timing on. Some flywheel mags have a advance curve built in, and seems to be perfect for best idle, yet revs up real good also. The engine I am talking about is a Mac MB290. You will see in photo below, I found this out with a timming light. I cannot wait untill they come up with a super light mag that will give good spark and weigh 1/10 th the weight. The rotor could be more flat and the coil could be thinner and hang in place a brake rotor. Come on guys...get to work and design one!!!! Capt,n

Please give us an “estimate” of the total amount of advance movement (in degrees) that YOU actually witnessed on that Mac implement engine,using the pictured timing light.
Thanks.
