I'm not sure how to ask this and I'm sure it's been over many times before and I've read here and there but would like an opinion from this group. I bought a 24" mill attachment and have cut maybe 700 bd ft so far starting with my 029, gutted muffler, 039 kit, done ok till the starter broke, then hooked up my 038 super, a little stoughter but still slow and week to me. I see these 066 chinese kits maybe $350 or so time it's running, are they junk or what? It took 20 minutes for one cut of a 2x16 yellow pine 12' long. Is this slow? Thanks David J.
