Motoringicons, you mention that you should back off the throttle and press the left pedal halfway. Regrettably, it's been way too many years since I was in the driver's seat, but I recall Dad gave me different instructions. The quickly/firmly motion rings familiar but the clutch motion is not. I'm not sure about the throttle. I was wondering the effects of shifting without using the clutch. Background, after numerous other cars, mostly T's in the Thirties Dad installed the Ruckstel and a Warford in his 15 roadster and drove in up and down the East Coast. He later installed this set up in his 24 hack which I drove a couple of times. I still have both cars and expect to get back to them after retirement. I'm looking for confirmation or "warning, don't do that", so that I'll have a better idea of how to drive it. I'm most confident these units were salvaged back in the day and doubt highly he ever had them apart for repairs. He just put a lot of miles on them. I also wonder what type of oil I'll find in there. Thanks
