Plus, since you have it running, you could make a mark where your sensor is now. Then advance it a small amount, test run it, etc. Once it quits improving in rpms, go back to your last setting before that and call it "good'.
BTW, 7500 on an 18 x 8 prop isn't bad for a Ryobi....
yea thats pretty much what i did.
I know 7500 is pretty darn good and i think the dynathrust prop take a bit of power to swing it. im not complaining i just find it interesting that all the stuff ya hear to make these run better most of it just dosent work. you know what my opinion is now lol.
When you time an ignition set up you DO NOT TIME the location of the sensor and magnet, there are too many variables in the sensitivity of the sensor and the strength and width of the magnet.
You set up your degree wheel correctly and turn on the ignition and rotate the prop hub in the direction of normal rotation, when it sparks that's the timing. Adjust until it sparks @ 28-30 degrees BTDC
Damn thats good to know. I dont know where i got the info to set it up in the middle of the magnet. I guess that makes sense to do it thais way. The only thing i dont understand is wont the spark be retarded for the low rpm or will it fire at full advance and if it fires at full advance when does it retard the spark? if you set it up this way then when its at full throttle will your total advance be 28-30 deg btdc? this 28-30 btdc is what the stock magneto runs at as i have confirmed this with a timming light and timming marks i drew on the engine shaft hub and flywheel when i degreed it in. I did notice when rotating it through that the spark was after the magnet was leaving the sensor so i knew the setting it in the middle of the magnet was bull at that point.
I got to say i was very dissipointed in no power gain going to electronic. I was sure losing the flywheel weight and drag and the drag of the magnet on the coil woild gain some power but no cigar on that one. well i guess if i get it timmed properly that may change. one thing for sure I do love the hand proping of it and how stinking easy it starts and idles.
