i have started to use aviation fuel in my "66"cc engine. it is rated at 100 octane and is leaded. so far so good. the acceleration is incredible but top speed has n't changed all that much. i am using a ngk 5hs? spark plug, which i undersrtand is the coolest plug i could find.
is this fuel going to ruin my engine or is it safe?
thanks. rich
