as a new member I wanted to introduce myself. My name is Karel and with my dad we bought an older (pre 2000) Yamaha 4AC engine. We are using it only on holidays in Croatia, so quite seldomly. After some years of service, it has developed a problem. It cannot idle or stay at low RPMs. The engine goes off immediately. At higher RPMs it works well. My dad cleaned the carburetter, changed the gasket between the carburetter and the cylinder, but with no success in curing the trouble.
So any hints are welcome.
Thanks in advance!!!
PS: a link to a repair manual would be appreciated as well
