I will recheck the timing for good measure (gear drive). I have only whacked the throttle up to say 2000 rpm in setting the timing.
Whats strange is the car saw no time slip change with short shifting at 6700 or 6000, jet change, only timing change from 42 down to 36 netted me a minus .5 mile an hour
Gonna be looking at the burn at the ground strap on the plugs next if there hot enough
