Talking about "hellfire" old double deckers, I'm join owner of a Leyland Fleetline that is currently under restoration, and on sunday we started it up for the first time in well over a year. It is currently lacking an exhaust, or the bustle over the engine, so was incredibly loud, although suprisingly not that smokey (infact the restored sister vehicle smokes a lot worse). Also, for some reason the normal starting circuit doesn't work, so the only way to start is is with a screwdriver across the contacts on the starter motor, and since it's 24v and on starting draws a few hundered amps we melted a few screw drivers (and rarther irritatingly one of my T keys that had been borrowed to open another bus), and the stop wouldn't work either, so the only way to stop it was the fuel cut off switch. The restored one is quite an experiance in itself, particularly for the driver, with leaf spring suspension, no power steering (despite this being almost standard by the 1970s), and a big tendancy to weave and understeer at anything like high speed due to the bad weight distribution.
