I’m saying I did push the throttle up with no great effect in speed. Sent from my iPhone using Tapatalk

The below pic is in MPH. But it Shows the affect of higher manifold pressure. Sent from my iPhone using Tapatalk

The throttle was not full forward. I have flown it at higher settings with the same speeds showing. Sent from my iPhone using Tapatalk

Negative on that. Twin Aviation in Georgia rebuilt the engine and although the price for rebuild seems impossibly low ($18k in 2022) they seem to have done a great job and all related documents for parts seem to add up. According to the previous owner, a mechanic did some work on the aircraft a while back and there was some angst between the two of them afterwards. I’ve tore the plane apart for the annual and found multiple items such as the nose gear doors being installed with the hinge facing wrong causing the doors to try and overlap, one gear was drooping more than the other when closed, and the cowl flaps cable improperly secured causing them to not open or close completely to name a few. It’s been an ongoing process of fly and investigate. I am building my knowledge at this time but may have to break down and see a service center at some point. As an A&P IA I hate doing that as I loose the experience. Sent from my iPhone using Tapatalk

Static RPM check is good and per the book. Did one on the annual a few months ago. Sent from my iPhone using Tapatalk

I’ll check the lifters. Haven’t opened it up since it was so recently overhauled. Compressions are all at 78/80. I have been finding a lot of items installed incorrectly, but haven’t discovered any issues with the engine yet. I’ve been babying it a little until the new chromed cylinders settle in though… Sent from my iPhone using Tapatalk

Could be. Since that picture was taken, I re rigged the prop lever as it was indeed rigged wrong with the lever bottoming out on the plastic interior piece. I had the mixture in a bit more as I’m breaking in the chrome cylinders and trying to keep the temps reasonable. Sent from my iPhone using Tapatalk

It was completed in 2022. Sent from my iPhone using Tapatalk

I’ve checked the mag timing and the engine has 20 hrs on the rebuild. Seems to be making adequate power and only slight mag drops. Sent from my iPhone using Tapatalk

AndreiC, the G5 was set to MPH on that picture unfortunately…. Sent from my iPhone using Tapatalk

As well, ground speed seems to confirm. Sent from my iPhone using Tapatalk

The plane just had its pitot static check a few months ago and true airspeed is coming from a G5. Sent from my iPhone using Tapatalk

I would be interested in and capable of making a copy rather quickly if I could locate a set close by. I would definitely like to retain a set as I may be working on others in the future. I am in Savannah GA. Sent from my iPhone using Tapatalk

Hello everyone, I am new to the Mooney forum and recently purchased a 1970 M20F that I am rehabing after sitting for a long period of time (I am an A&P IA with limited Mooney experience) as well as having been worked on by many others without significant flight time afterwards. This plane has the J model windshield and speed mods. I am only seeing about 126kts true airspeed at altitude regardless of prop and power settings. I’ve checked and rechecked the gear rigging and it is within tolerance, however I will be mounting a camera to check for any flex or droop from the doors in flight. I am in the process of locating throw boards to check the rigging as she does seem a bit right wing heavy and needs a slight touch of right rudder to hold true. I’m reaching out for any suggestions as well as experience as to what could be the most likely cause for loosing so much speed. I’ve heard they will not max out on speed without being rigged perfectly. Without the boards I’m limited, but everything appears to be in good order rigging wise with the flaps and ailerons.

I am an A&P IA and recently purchased an M20F. I am looking for a set of aileron rigging boards. I’ve seen the topic brought up a couple times on here but they seem to be from a while back. Does anyone have a good contact for drawings or the boards themselves? Thanks for any info. Sent from my iPhone using Tapatalk
