My last carb car would chug up surpringly steep slopes at 300rpm. Much easier to deal with than an electronic engine.

I've never driven a petrol-engined car that would even *idle* at less than about 600-700 rpm without faltering and stalling, let alone one that would do this with any mechanical load. When I was doing a car-maintenance course, we looked at adjusting idling speed with an accurate tachometer and I think my Renault 5 with a 1300 engine would idle at about 640 rpm - just. If you adjusted the carb to make the idling speed any lower, it would falter. The course leader demonstrated that at the critical idling speed (and normal idling speed is adjusted to be a bit faster to provide a comfortable margin to avoid stalling) even rubbing the handle of a screwdriver on the fan belt applied enough extra mechanical load (over and above the frictional load of the bearings etc) to make then engine falter. I was most impressed with my Peugeot's diesel engine. I was going up a 1:3 hill (Rosedale Chimney in the North York Moors) when the car in front of me stopped- maybe he'd stalled. I was apprehensive about having to do a hill-start on a 1:3 hill once he eventually got going again. When he did start moving, I left a gap before setting off, with a reasonable amount of accelerator, but the silly sod proceeded to go up the hill at about 1 mph. Even with my foot off the throttle and in first gear, this was too fast for my car and I found myself gaining on him. But the car pulled quite happily at idling speed. I realised that I'd have to slip the clutch to keep going at such a slow speed as him, so I stopped for a while till he'd got a long way ahead and I could drive at a normal speed.

I may stay in gear with the clutch down if I anticipate that there > will only be a very short wait, Me too for different reasons, the Fiat has a tempremental cooling fan switch and tends to overheat in stop start traffic so I switch it off if any stop seems likely to take more than a few seconds. Got in to the habit now the Fiat restarts instantly but when I try this with a Saab it lets you know it's not happy.

All the petrol cars I have had, if you take your foot off they slow to a stop and stall. Diesels tend to carry on, even in higher gears. -- Mike. .. . Gone beyond the ultimate driving machine.
