Great, thanks ever so much

Thanks Spud, I appreciate your response The saws I have are; a stihl 660, new and two old stihl 028's that I just rebuilt with new cylinder/pistons. Do you think on the 028's I should drop the 1000k being they have new cylinders? Oh and my neighbour has a Stihl 026 he needs tuning, if you possibly know the max rpm's on these saws? I was just going to take them a stihl store to get tuned but they wanted $100 each to tune! Worth buying the $85 tacho. How much of a screw twist is there generally between rich and lean? It seemed more of a screw twist than I expected on the 028 to get the different sounds. Do you know whether a fuel/air meter even exists for chainsaws, although I think by ear with the muffler and its restrictions still on is the better way to go. Thanks Chris

Hey everyone, I just ordered the DTI Tech Tach TT-20K and I was wondering if you guys could point me in the right direction on a few questions; When setting the h-screw, say your saw spec is 13,000 rpm max, is that exactly how you set it regardless of fuel/air ratios? I'm assuming 13,000 is just a guideline and there is a + / - to get your saw sounding right? Also if the above is the case is there any fail safe way anyone has done the fine tune, has a fuel/air metre been used by anyone? I am not that confident on setting the L-screw by ear either. Thanks Chris
