hello! I just joined the site and I know that I need a petcock for my moped (oil leak) but I am unsure as to where I would find one for my make and model. I got a great deal on the bike so I am also not unhappy about possibly needing a new corroborator? it’s a 78 jawa babetta. I know NOTHING about this bike other than that. I WILL be seeking professional help within my cities resources but I need to know where I would go about parting this bike. Thank you!
