Good luck, I have heard good things about Barry mounts as well, which will probably save you about $100 over the Lord mounts. Maybe someone else can ring in on that. This is a good read, even if you're not participating, it's good to know the process. As I said before, I don't think it's good if you can feel vibration through the yoke an seat... http://www.donmaxwell.com/publications/MAPA_TEXT/Alining%20Engine%20Using%20Shims/ALIGNING_YOUR_ENGINE.HTM

Quote: SkyPilot My 1967 M20F is a whopping 1800 pounds. It has some minor avionics upgrades but still has the Narco 12 and an antique ADF with wire sense antennae. These items will come out this winter and a skytech starter will go on. Other mods are electric gear and 3 blade prop. Paint was new in 1995. I'm also planning to get a new up to date weigh-in. If anybody has any good weight loss ideas, i'd like to hear them. It will likely be easier and cheaper for me to drop 30 pounds

.01 IPS is actually quite good. It stands for "inches per second" and is a measure of amplitude. New lord mounts should last longer than 500hrs and 10 years IMHO depending on climate. Instead of replacing, you can also swapping them around. I would check to see if the engine was properly shimmed at OH. $hit happens and sometimes planes go out of the shop without all of the finer points being attended to. 4cyl Lycs are not the smoothest engines for sure, but vibes in the yoke and seat = bad juju. I don't see how it could be shaking so much and read .01 during a dyno... I'm in KFDK and keep my F at KHGR. I'm an easy 45min flight from Mt Pleasant if you want to compare/contrast... Let me know.

1967 F Empty Weight:1684lbs Useful load: 1056lbs Fuel Fuel Payload: 672lbs If we'd remove the old remote compass, ADF and some other crap, we could break 700lbs for payload.

My MX manual for a C,E,F,G calls for MIL-G-7711 (AS#6) or MIL-G-81322 (AS#22)... I just keep #6 and #5 around. #6 for the airframe and prop and #5 for the wheel bearings.

My peak EGT will only top 1500 down low or on cold high pressure days. As I said, I am almost always WOT unless descending. I fly LOP over peak under 5000 because I can develop plenty of power and keep CHTs low and best BSFC is achievable at good speeds. My stock F model will run 145kts+ LOP at 4500 to 7500 and a little faster down low.

Dave, that totally sucks. Why would the fact that the hydraulic flaps share the reservoir cause an issue? Hopefully Paul can get you squared away. Do the logs not show who did the install???

Quote: testwest Ross is mostly correct. At that power you need to be either 250 degF ROP or 80 degF LOP to be out of the red box. JimR, you are correct that 80degF ROP is max power, but it is also in the dead center of the red box when above 90% power. At that power and mixture you may eventually build up enough heat in the cylinders to cause detonation. It certainly is hard on the engine....
