Re: engine siezed - fix or replace?
A whole engine is $80 + $16.99 S&H = 96.99
If you send in your old engine + $60, this means that the engine is worth $36.99.
The old engine has the crankcase halves, magneto, magnet, clutch parts, that if bought separately would easily exceed $36.99.
I would keep the old engine for parts/rebuilding and a learning experience, unless you're hard up for loot.
