I have two engines that are nearly identical.
One came off a Stihl weedeater and the other one a Ryobi.
Did Ryobi make weedeaters for Stihl or visa-vesa??
Anyway, the Ryobi one seems lighter to me.
Its the one with the black plastic backplate on the motor.
The white backplate is the Stihl.
Which one should I try to convert?
And if I decide the Stihl, will the conversion kits for a 31cc Ryobi fit it?

One last question, I know I have to have the factory flywheel milled down some.
But how to I get the metal pins out of it that the starter sprags rotate on without damaging
the flywheel itself?
I don't want it to blow up on me!!

Thanks
