You need o be carefull with the tuning as the JTS engine runs at very low RPM/ low load with stratified lean type combustion where a small rich region is created around the sparkplug in order to initiate combustion. At high RPM/load the combustion is stoichiometric homogeneous. What i want to say in simple words is that messing about with ignition timing during the first case will cause misfire.
