The other day I saw my neighbor at church and long story, short....he dropped off a STIHL 028 Wood Boss AV with the "electronic quickstop" He claimed that his dad had it for years and then passed it on to him, he ran the guts out of it until it started "loosing power once it got hot." He also gave me a Homelite Super XL auto that seems to have compression and I know no details of, because I didn't know he was leaving it lol. Anyway after initial inspection of the 028, it seemed to have good compression and the P&C look perfect. The only thing Ive noticed is that the whole flywheel side, especially under the starter cover, it's excessively caked with grease. Not sure if it was just from bar oil being spilled down the side time after time, or if there's a leak (common or not) there's somewhere. It was so bad that the flywheel had a path worn through it and you could barely see the side of the coil hahaha. Wondering if it was enough to cause firing issues with the coil it was so nasty. The contact points on the flywheel and the coil were totally covered and had to be thoroughly cleaned. I took all the covers off and cleaned everything and took the coil and carb off as well. So now I need to know how I should proceed. Should I take it down further and replace the intake boot and fuel lines for good measure (but they seem fine) or should I re-install the coil and carb and see what it will do? Mine also has the 3-piece muffler....what's the best way to make it flow good? I really don't like how it dumps the exhaust directly down into the case, but not sure what to do about it other than weld it shut and make new exhaust ports??? Also do they benefit dramatically from a gasket delete and/or porting, or should I leave well enough alone, so long as it has good compression? The saw looks really nice, aside from the staining from gas/oil. It's been stored in the hard case all these years and I got it too
