If you mean your very first start on a fresh engine, about half way round the block.
My legs were caneing first time I fired my engine into life.
Half way round the block I stopped and started checking everything as I was sure I did something wrong during assembly. But then on the way back I decided to pop the clutch for the **** of it and after a couple of meters she spluttered into life.
Oh, I forgot to mention that when I pop the clutch I hold the throttle open a little. Any more than that wouldn't do any good since the choke is closed. Once it starts I open the choke to prevent it from flooding out.
When I took out the sparkplug and looking in the cylinder, I didnt see fuel. However, I did not get a chance to drive it around the block only a couple feet at a time untill the chain jammed up on me. Does that mean anything?
