Ryobi ignition timing
 
At what point does the magnets in the flywheel trigger the coil to produce the spark at the plug? As close as I could tell was as the magnets passed the core of the coil was about 3/4 the way passed. I used a degree wheel and if the Ryobi has a timing of 28 degrees BTDC. Also if I increased the timing to say 32 degrees BTDC would that increase the RPM? :eek:

It might...you just have to try the 32 degrees. Watch out for kickback if you get the timing advanced to far. Capt,n

Increasing the timing might increase RPM and power. You can do what we used to call power timing with the engine running, but, in a plane with the prop it would be very risky. Don't do it. Besides in these conversions I have timed them from 25 to 35 with CH ignitions and you really can't tell any difference. Too much and you can get bit flipping the prop if you are not careful.

I don't see how you could move the flywheel with the engine running, that's why I use a degree wheel.[&o]

Come on guys be nice. I was referring to electronic ignitions we ran on karts years ago. Guys would "power time" them. Usually they would melt the engine too but for a while they ran like crazy.
