My 71 B will diesel if given a chance. I found that dieseling is VERY
sensitive to rpm and throttle. If you want to experience some really dramatic
dieseling, hold the throttle down when you turn the ignition off. A low idle
speed will help reduce dieseling. Working the clutch (foot on brake) to shed
some rpm just as the ignition is turned off, works great. Always make sure
the choke is all the way in before switching off (so the fast idle is off).
Octane booster helps but is an expensive pain in the butt. Don't use regular
or you'll get pinging to go along with even worse dieseling!
