You may cause a lot of damage if you lean out the engines. Holed
pistons, burned exhaust valves, running hot can be the result if you
overdo it. As the engine becomes less efficient you will use more fuel
instead of less.
Burned valves are usually caused by the valve clearance to tight, heavy
load at to low revs, lean mixture and/or incorrect ignition timing.
For all these vehicles stick to about 6%CO min. idling.
