In the past 6 months I have had several problems with my son's Blaster.
1. Stock at the time, Piston broke.
2. B1 Toomey kit added, new top end and than my bottom end went bad (main crank needle bearing went out. 310 main jet was added no air box lid.
3. New bottom and top end. Same 310 main jet and no air box lid
4. Top end burned up (only 1/2 tank of gas).
So, I have rebuild the top end again. Upped the main jet to 330 and completely closed off the air box.
Here is a picture of my 1st plug chop (yes, rookie move and cut too deep) and need help understanding what I'm seeing. I think it's running rich now, but want to make sure I'm doing things right.
