My c90 has a very weak spark and is a pain to start and after I have it running it pulls away in first like its in third!
now I was informed that because the battery is not holding its charge for long all the current produced by the generator is going to battery instead of coil thus causing weak spark.
if so surely I might just as well remove the damn battery as it doesn't do alot when its running anyway and all that current will go to coil instead of elsewhere?
