It will start much easier with the timing retarded and the necessity of snapping it past the magnet contact is gone,but you said you have mastered starting.The weight advantage is very little on this particular conversion combo,and not worth it IMO,since the flywheel is already vestigal,a part of the coil system remains in place on this conversion I beleive ,and you did not say you were using a spring starter.It will improve the idle,but only you can decide if its worth the $.If its nearly new,an option is to sell it and buy aFox,Bison,taurus,ZDZ etc...which are designed with an electronic ignition,and which will be quite a bit lighter too....As time goes on you will see more and more G62 type engines on the used market for this reason IMO
