What should the manifold pressure of a IO-320 engine be at around 1000 RPM? Today, while doing a brief engine test, it was down around 16-19" for RPMs around 750 to 1000. For an earlier engine run at 1700 RPM it was around 23", which seems normal, but I didn't keep a record closer to idle RPM back then. What I was getting today seems a little low, but I have never flown an airplane with a MP guage so I have little frame of reference here.
Thanks.
Thanks.
