15 SP850 Rebuild
Picked up a 15 SP850, all stock. Only has 72 hrs on it. Guy says it backfired then quit running, then wouldn't start. Check compression, rear cylinder was good but front cylinder had 0psi, none. So I Pulled motor, started the tear down, The top of the piston above the top ring has broken apart, causing some damage to the cylinder head, not sure if theres somewhere that it caan be repaired or not as its not cracked or has huge gouges in it. The rear cylinder that had good compression has part of the top of piston broken too.
1: how to tell if the cylinders are nickasil? Dont you just stick a magnet to it and if it sticks its iron?
2: Posted pics of combustion chamber of cylinder head with damage, anywhere that could possibly repair this instead of buying new or good used head?
3: Is it completely necessary to pull flywheel to split case? Ill order the special tool if i have to I just dont see why it would hinder the bottom end coming off
