The Monaro runs...just
The rings are shot, among other issues with the g3 carby. but it ran for a minute until I earthed the plug. Cold started it later, went first pull (strange given the rings).
All the Ryobi needed was the metering diaphragm installed properly, metering lever height reset, new air filter foam and carby tune. It has a almost brand new clutch in it (definitely not the original).
I feel a bit bad for the person who obviously put some money into this and couldn't get it to run (due to the metering diaphragm). Runs nicely and has plenty of torque. .
