Re: Both magnetos cracked!!
Dude (and TD), Grade 5 will work fine. Now WAY they will strip out the FW, any easier than Grade 3. 5, or 8 will..ya just have to do the following (Machinist all my life) ..... ..tighten them snug,
then tighten the center screw super snug ...strike it with a 5lb or better sledge. Don't beat it down ..what you are looking to do is shock it off the taper. Rap, tighten the center screw down again, rap...it will pop off..its the shock that breaks the taper..not the puny 1/4 bolts..I've done enough Flywheels that I just stick a heavy duty screwdriver under the flywheel and a solid piece of motor block, crank nut almost flush, and rap the SOB my my 20 pounder. But it takes a lot of doing it before ya get the feel..talking lots of years here..(yeah...busted a few wheels too!)
Stop saying magneto...a mag is a self contained magnets and rotor...you don't have one..its the coils that are junk...you will find many small pieces of the coils when it comes off. $40 for 2 new coils, ya back on the water again. Hers what you will find
