[ercoupe-tech] Fouled Plugs

[robertbartunek]

With the use of 100LL I understand there is some concern about fouled 
plugs from the lead content.
Way back when I was flying round engines, we had a procedure on every 
shutdown  to lean the engine to just prior to rpm "stumble" at about 
1700 RPM for three minutes to "cook" the plugs and burn off the lead 
deposits.   Anybody heard of a legal procedure like this for 
Continental engines?
