I've never really had the money for the best of the best on my blowers and trimmers so i have to make the best of what I've got. Let me start off by saying I know this is illegal, unenvironmental, etc. I'm in this biz to make money and find the most efficient ways of doing it. I don't get paid to worry about all the little crap in life and I don't think anyone on this site does either so spare me the preaching of how wrong you think this might be. I took my 2 cycles and made the air filter system better breathing(homemade), turned up the Hi needle on the carb to a safe enough setting that I won't hurt the engine(believe me there is plenty more RPMs to pull out of them from the stock setting), and last but most importantly you NEED to gut all the EPA and firescreen crap from the muffler and free it up. My end results are 2X the power, yes 2X. Burns less fuel overall, gets the job done better and FASTER, and way easier starts. I always wondered why some of my 2 cycles were so hard starting and after I cracked into the exhaust I could believe they would even run at all. They all totally restricked from the factory. I just thaught some of you might want to try this technique and I'm sure some will wine about the legallity of it. Bottom line it works great.
