Hello Brother, nice work👌 This flywheel stock 3120 or have some modifications? I heard after installation from 272 coil to 3120 need upgrade flywheel or just replace it, and adjustment timing
The flywheel in mine is upgraded to the post 2001 limited coil/flywheel package. It had the pre 2000 package. So I think as long as the coils look the same it can be upgraded as shown with some filing inside the bolt holes for the 272 coil
3120 new 1695 to 2700 new crazy much rather 084 122cc 088 880 121.6 cc even 075 076 111cc just better saws 090 137cc is the biggest stihl made fun big old saw
