HI there guys
I have been stalking this site for the last couple of years whilst restoring what was a very sad 1100ET, and now I need some help and advice.
Yesterday I started the engine for the first time in a long while after rebuilding the top end. I was about to balance the carbs and after warming the engine up I put the vacuum gauges on but left the tap open on the auxiliary tank then went to start the engine, it turned over once... did not fire but then there was a very loud mechanical bang and the engine stopped turning over. I thought about it, took out the spark plugs and turned the engine over then fuel came out. Please can you tell me why it did this and have I damaged the engine conrods ? And is there a way to find out if I have done damage without stripping the engine ? I know you like pictures, here she is when I got her and where I am up to.
