Me and a friend built a car with a 2 cyl Archimedes engine when we was 10 -12years old
With ropestart, that kind where you have a knot at the end
of the rope and wind the rope around the flywheel.
We could not find the carb for it so we tried with a Norton
Dominator carb, not a sign of life so we gave it a dose with
the oxy/acetylen welder.......i sat in car and held a bit of throttle
With the velocitystack pointing at my face and friend pulling the rope
Fjuff Fjuff Fjuff KABOOOM it backfired so hard that the rope
Pulled my friend over the engine and the flame out of the stack
Torched my eyebrows and hair
