does anyone know of a harmonic balancer that can be made to fit an a15 engine.the race engine in the sunny has a serious harmonics problems from 7000 rpm onwards,& has almost shaken the starter off once,done in two oil fittings,& vibrated loose the oil filter.i know it's not a balance problem,as the motor was fine with the old,smaller cam in it,but this new cam is making so much power that the crank is flexing.i have a long term solution,but that will take a couple of months,so i need to get a harmonic balancer until then.a friend how had one made up for his a15 (same cam,same capacity,same problem),says someone told him a balancer from another engine would fit,but he can't remember who told him,or what engine the balancer came from.please,if anyone knows for certain,let me know before the flywheel drops off & ruins the crank.
thanks, paul.
