need advice for breaking in an engine
Just got my engine rebuilt, just after the previous owner had rebuilt it already. When I bought it, it had a valve tick and it turns out that it had a burnt valve and bad piston on cylinder one. Everything else was in good shape so I had a builder replace the piston, and just go over the rest of the engine. Now Im a little worried about damaging something else again as I'm not exactly sure what cause the burnt valve the first time. I'm not too confident in the tune it currently has. Will starting the engine and idling be a good idea?
