I just finished this build. I purchased a brand new OEM crankcase from a trustworthy member on this site. It had the crank, bearings, seals, and crank sleeve factory installed. I put a brand new OEM top end kit on it along with a brand new OEM top cover, OEM air filter cover, and OEM starter. The chain brake is also new OEM. I installed a used OEM oiler and it has a used OEM unlimited coil. The handle is used OEM. It does have a new aftermarket tank, new aftermarket exhaust, and new aftermarket clutch cover. I did make a few upgrades. It has the oversized OEM dawgs on it, the flip style gas and oil caps, and the upgraded metal flange for the throttle cable. This saw is solid and basically new. If you have any questions, please ask. It has less than a tank of fuel through it since was put together. It has great compression and runs great. I didnt install the compression release on the saw, I plugged it instead, but I can swap it if you want one. $725 plus the ride. Paypal F&F. If you add the cost of the new OEM parts, Im barely under break even.
