Hi!
The engine doesn't get fuel! Open the highspeed needle.

But, i started the car, then it ran for about 10 seconds then cut out, so could it be something other than the highspeed needle, or could that have been the petrol in the engine buring, then there was not enough getting sucked in? Also how much should i open the high speed neddle?

Cheers

P.S - what would a little bit of sugar in the petrol tank do? Would it wreck the engine?
