If you cannot find an original Mega P/S, your engine is paperweight, sorry to give it bad news about this.
Alfonso,
are you sure about that? I have two older NovaMega engines, and both have the pin at the exhaust side like any other NovaRossi engine.
I'm pretty sure that I rebuilt them with NR P/S sets in the past.
STS have the pin on the carb site though.
