Hi, I don't know if I'm asking for the impossible but I'm looking for a way to measure RPM fairly accurately but most of all cheaply. I recently bought an old piece of garden machinery powered by a Briggs & Stratton 3hp engine which runs fine, though it seems to be spinning too fast, I know how to set up the carb but it rather depends on setting the idle speed at 1750rpm. It would also be useful to know the speed at full tilt. I was wondering if there are any reasonably priced tools available or any tricks you chaps know of that might help me out. Sorry for rambling on a bit, many thanks in advance for any help or advice, cheers, Andy Hubbard
