    Break in after rebuild?

    Does the engine need to broken in again after a rebuild? I'm helping my friend rebuild his engine and all we're doing is replacing the conrod. The piston and sleeve are fine.

    I've actually have two 3.3's to break in, my Revo and TMaxx trucks. The way the carbs come from factory, do they usually start up for break in without adjustments? I now I'll need an extra glow plug on hand. My 2.5's run like junk Previous owner trashed them, and from the condition they were...
