My fickle little Italian racer, a mashup of Lettera 32 engine grafted into a sturdier Lettera 35 body. She'd be so nice if she'd just run reliably. Her problem seems to stem from either the carriage locking mechanism or a tiny cog buried deep inside the escapement spacing mechanism. It happens so sporadically that I haven't really nailed down the cause or a fix.
