I’ve been busy lately getting all my chainsaws running properly. After some general cleaning, new plugs and a couple of carb kits I have my whole fleet of stihl saws running good. I have always adjusted carbs “by ear” but thought it might be worthwhile to have a tach to set the hi speed adjustment on them. Does anybody have any of the inexpensive tachs that i see for sale on line and do you like it and feel it works well for the speeds modern chainsaws turn. If so what brand/model do you have. Thanks for any input you can give me
