After Doug Sappâ€™s posting about the availability of replacement instrument panel dampers, I took a look at mine. All eight (forward and aft cockpits) were totally shot. Since they are not readily vi ...

One additional item. If not already done. The bottom thread of the snot bottle will need to be tapped to accept the input side of the Swagelock valve, which I believe is Â¼-inch NPT. After completing ...

Hello Mark,
For the Yak-52, it's the Swagelok SS-43GM4-S4.

For the CJ, a typical install requires a right angle adaptor and a different right angle Swagelok valve. If you need this part number Iâ ...

Here is a picture of my CJ emergency on-off valve with adaptors that duplicate the original line positions. The Yak-52 probably requires different adaptors. The black handle valve for the main air is ...

Gents,
I ordered two of Richardâ€™s mag coils a while ago. Lovely workmanship and quality. Highly recommend.

After taking apart the mags to install the coils, my mechanic told me that for the tim ...

You would have to ask them. If the Barrett HC pistons extend higher up into the combustion chamber, there could be serious problems.

Gill,

The unused switches can certainly be used for other applications. I have one assigned the task of turning off and on an electric boost pump and another is used for my strobes. I believe that ...

Jon,
Mine was also one of those unusual CJs that had this same air scoop. Did not appear to serve any purpose, so I later removed it and filled in the hole.

Here is a picture taken the day it was ...

Iâ€™d say radials are not only reliable but robust. On the way to an event, my M-14P started shaking and the CHT indication slowly decreased to less than 120Â°. Bottom line was that I lost power in th ...

Had the same series of events. Problem was solved after replacing both of the original main gear actuators.

Another way to find leaks is to use a hand held ultrasonic leak detector. We have four CJs in one hangar and this equipment is shared by everyone. Itâ€™s capable of uncovering even the smallest leak. ...

If you have a M-14P with stock pistons on your CJ, something additional to consider is running the extended depth BPR6HS NGK plugs with the gap set at 0.020 as Dennis has recommended. Most are using t ...

Iâ€™ve used the Brackett filter on the M-14P of my CJ for years. No significant loss of power noted. Might be over-doing this, but I change it every 50 hours.

Here's an image of the packaging. As ...

Jeff and others,
Happy to help. Will send this to you off-line.

The aft cockpit passenger told me that they were doing a touch and go landing at FFZ. During the climb-out, at about 60 feet, the engine seized… prop abruptly stopped turning. Local TV reports are tha ...

Gents,

I totally agree with Larry.

Have used the Westone molded ear plugs / integrated speakers with a military helmet for several years and they are amazing. Later, had our local hemet guy add ...

Jan,

I also have the small Becker radio in my CJ, in addition to a Garmin SL-30 as my primary radio. Liked it so much, I replaced my transponder with a one by Becker. In spite of their small size, ...
