Spark Issues

I have a 96 honda 300 fourtrax. I have been reading this forum to find help with my problem. I find lots of posts that say "no spark" but I am getting a spark, sort of. It just seems to me the spark is "weak" and kinda jumps around.

One day it was running fine and I shut it off. When I tried to restart it wouldn't start. I checked the plug to see if it was getting a spark, and the spark seemed weak to me. I put in new plug and it firied right up as soon has I hit the button. It ran fine for three days and now same thing, (exept now the start button wont work I have to jump the solinoid next to the battery to get it to crank). While it cranks I can barely see a spark.

Question is where to start? Are these two seperate problem?

Does anyone know of a good online schematic or repair manual?
