I want to do a muffler mod on the Husqvarna 36 that I recently got going. Ive been reading some about this and I think the best way I have found on this one is to drill out the baffle holes as large as I can and cut two slots in the front of the muffler. Afterwords I will need to adjust the carb correct? Will the whole thing need adjusted and if so what is the adjustment procedure? This is the replacement Zama carb and still has the factory adjustments that it came with.
