Brilliant thread, I am about to start a project on rebuilding an early series 2 with the series 1 engine. The engine in it starts and drives but I know the rings have gone as it blows oil out the breather. The only issue I can find on the engine is that a plug on the exhaust side of the engine blew out a few years back and I didn't have another one handy so I used numetal to plug it up. I posted a pic of it so could someone give me some advice on what the plug is?
I live on the Northside of Brisbane and would love to come and have a look at Matilda when she is going.
