I have two CMB HRs and a 21 red head cmb for sale. From what i seen so far the 45 is clean. I replaced bearings in one. Both have good pinch and been stored in boxes with after run.The 21 i never ran so im not sure the bearings and has decent pinch. Im going to post more of 45 later. Ship only...
Now that i looked i have a flywheel for a cmb 21 motor unless they are different motors. I imagine all cmb 21 flywheel are interchangable. Thank you for the offer.
