Rebuilt from the "case" up with Nachi bearings, Cross Performance seals, kitted HDA-159, new fuel line. Steel intake clamp. At some point in it's previous life the muffler came loose and melted the oil tank a little. It doesn't leak. I've added a 351 style muffler bracket. Timing advanced, muffler opened up under the deflector. The bearing cup divider has been removed and the square edges in the lower transfers and the cup have been smoothed. It has a Hyway 45mm popup piston. The base gasket has been deleted and the top of the bearing cup had .010 taken off. Squish is .021. Compression is just north of 180psi after 4 tanks. This is an easy starting, good running saw. The throttle response is very quick. I've had my fun with it and have everything to do another. I'd like $225 for the powerhead wearing your rim sprocket of choice. As usual, questions and pic requests are welcome.
