bought used. coils been replace , new plug wires , new spark plugs, took out plug grounded to block sparks but looks real weak ? also battery weak ? please advise, I was wondering if battery could be given the problem, but I also used a jumper didnt seem to help.

i would try a new battey and of that doesnt help then the best thing to do is disconnect the ignition switch and any kill switches and try and short the two main starter relay wires out and see if the spark is any better then,if not then the only thing left is the primary ignition coil in the generators stator coils this is very common on motorcycles and jetskis alike.
