Recieved a new STS 30 today. I have removed cylinder, mounted the flywheel (too hold the crank), and trying to remove the piston (with the piston at TDC), using a zip tie under the conrod. It is so hard to pull off that i am afraid too destroy it.
Anny tips???
rotate the engine between 11 o'clock and 1 o'clock as you rotate the engine
Thank you.

Changed the bearing to Boca high speed/high heat. The front bearing has metallic retainers on a high rpm engine???

Pictures of the original bearing compared to the Boca bearings.
