At 20 MPH my RPMs are reading 4500. Flapper wide open. Engine isn't
sounding like 4500 RPM. Took it up to 25-30 and it was in the 5500
range.
Does/could wide open flapper cause that?
Or am I getting false reading?
Can tach be calibrated/tested?
I'm gonna take it out today. Would to go faster than 20. But don't
want to break anything.
