Just sent you an email about renting your shock disc tool. Thanks, Paul

The snubbber worked. I used a .004 from McMaster-Carr. Omega had a 9 week delivery time. Like you said "Ragsf15e", it is always the last thing.... Thanks and this will be the final post.

Thanks for your reply. I have read about the snubber before, but JPI's current tech support says the problem was fixed with the newer units. After a conversation with the tech support I found him lacking in personality and willingness to help. My installer had told me earlier that was their opinion as well. That being said I think I will try to find a snubber and hope that works.

The problem started after the new install. Zephyr did major overhaul of the engine in September 2019. When the airplane went in for the new panel upgrade it had a JPI 830 and a Electronic International digital MP gauge with no problems.

I have a 1992 M20J and did a panel update late last year that included updating from a JPI 830 to a JPI 900 engine monitor. Since the install the manifold pressure has been constantly fluctuating as much as a full point either way making it impossible to accurately set power. JPI sent a loaner unit that did the same thing while they did a software update to mine. New unit came back with same problem. Next, JPI sent a new sensor that did not resolve the problem. Went back to installer and they moved the sensor from the #1 cylinder to the back of the engine baffling with no change. Plane just came out of annual, and we replaced seals and gaskets on all 4 intake tubes with no changes. Wiring has been checked twice by installer and my mechanic. Any thoughts or suggestions?

How about for MaCauley prop? Also which way do you turn the screw to increase rpm? Thanks, Paul Sent from my iPad using Tapatalk

They adjusted the autopilot. Mine was also tracking well left of the magenta line and they adjusted that out as well, again thru the screw hole in the face of the autopilot. Paul Sent from my iPad using Tapatalk

I just had a Pro 1000 installed and when I left the shop it would barely do half rate. I have a KAP150 and it only took the avionics shop about 10 minutes to adjust it. Works fine now. Sent from my iPad using Tapatalk

Thanks for your response anthonydesmet. I was quoted a vacuum RC Allen attitude indicator for backup, but we just finished the annual inspection today and now I am leaning toward adding a G5 to the installation and do away with the vacuum system. I have a backup vacuum pump system and should be able to defray some of the cost by selling it. I will be pricing the addition tomorrow and hope to have installation done in December.

Do you know if that includes the EA 100 autopilot adapter for the KAP 150? Sent from my iPad using Tapatalk

Thanks For the reply Chris. I thought the equipment prices were ok but the labor which was included was over $4k and I thought that was a little high. I have 2 more quotes being prepared. I will ask about rebate. Sent from my iPad using Tapatalk

Coming home from avionics shop Thursday my KI-258 attitude indicator decided to take a nap. It was overhauled about a year and a half ago with less than 200 hours since, so it has me thinking about upgrading the panel. I would be trading in the KI-258 core, the King HSI system and a DAC GDC-31 GPSS unit. In return, I would be getting an Aspen 1000 Pro with EA 100 autopilot adapter and a new RC Allen Horizon Gyro for backup installed for about $15k. Opinions on whether the price seems high or about right. Thanks, Paul

Done. Thanks Sent from my iPad using Tapatalk

I have had very good dealings with Jimmy Gaither and Southcoast on the prop on my J.
