I have a Ryobi 26cc 4stroke on the bench alongwith the Stihl 4 stroke.The Stihl hands-down has much more power and rpms. I guess I'll have to fireup the lathe
and make a shaft extension so that I can use the factory mag with it. I don't have weights for each of the engines, but it appears that the Stihl is noticeably lighter. I also like the
fact that I don't have the added weight of engine oiland a sump to deal with like the Honda and Ryobi.I know that my local lawn mower shop has afew more of the Stihl weed whackers available, so
I might buy one or two more if this conversion is successful. He's a Stihl dealer and is more than happy to sell me what heconsiders "junk". I seen that he has two shelves full of dead chainsaws, so Iguess I'll have to check them out on my next visit.

Where is a good place to buy an electronic ignition? Maybe I need to come out of the stone age and try one...lol.
Thanks,
Larry
