Still having problems with my RPM's being to high. When I start it, it stay's around 1700 RPM's. From what I've read on this site, it sounds about right. Then, after letting it warm up for 10 min, I'll rev it up a few times. After doing this the RPM'S stay at 2500. Is this normal? I don't recall it doing this last year and the only change I made was adding new reeds.
