Thanks everyone for the feedback! I'm definitely going to look into the muffler ordeal.
Thanks porkchop! I learned about the tightening nuts and bolts the hard way-lost baffle-in any case I make it part of the routine to tighten down nuts and bolts.
Any of you guys look into lock tight for the screws/bolts?
What about weather proofing magneto cover?
One more question
