RE: Stihl four stroke models....
I got a FS110R string trimmer for $10.00 from our local lawn mower shop. I came home with it and setit aside. Last weekend I decided to see if it started and it did without muchcoaxing and ran like a champ. Long story short, the crankshaft is barely as long as the flywheel which makes it useless for a conversionengine.
