I was running it ROP. Thanks for the advice! We will see what we can figure out tomorrow...

Good point Don. I was thinking that might be something we need to look into.

Yeah it does have download capability but I really have no idea how that is done. It is one of the early models, Insight GEM I believe. I think the plugs have around 250-300 hours on them so it may well be time for a new set. What model Tempest do you use in your Mooney Scott?

Not sure, I think they are champions but not sure which model. Not sure if they were measured for resistance. How is that done? Mechanic is meeting me at the airport in the morning to test it out with me. We are going to run it up and if everything checks out on it will fly it. I was telling him about it all and he was not sure what it could be.

So I flew my Mooney today for the first time since it came out of annual and had a few strange issues. Flew up to KGLE (Gainesville, TX) to top off the tanks with fuel, only about a 30 mile trip from my airport. Flying up there everything seemed fine and worked like I would expect it to. However on flight back shortly after takeoff engine started running a little rough sporadically. I never had a large loss in power i would say if any drop it was less than 100rpm, but you could tell it was cutting out or missing. The glare-shield would vibrate a lot when it did. It would only run rough for about 2 to 3 seconds at a time and then clear up and be fine for 20 or 30 seconds and then do it again. The other odd thing was the #3 cylinder on my insight engine monitor was reading really low and sometimes it was even not showing any temp Reading at all. Number 3 would occasionally bounce up to the normal range with all of the other cylinders but for most of the trip it was very low. Fuel pressure looked good. I checked both mags in flight and they both seemed good, very slight drop in power but prob less than 25rpm each. The cutting out/rough running of engine appeared to happen more when I would adjust manifold pressure, as I got within about 8 miles of my airport I began to inch mp pressure back. As I did this I noticed less cutting out/rough running of engine and the number 3 cylinder on insight monitor read a more average reading that was in line with the other cylinder CHT and EGT readings. My first thought was water in fuel or ignition. After landing I opened the cowl to see if all plug wires were connected well and they appeared to be. Nothing obvious that I could see wrong with the cowl off. From the way it was running i thought there might be some arcing so i looked at spark plug wires but they looked good and are really not that old. Pulled spark plugs on number 3 as well. They looked good.... I sumped tanks for water and there was not any. The dual mag was pulled off and overhauled this annual. It was running perfectly before the annual but since the dual mag had 514 hours on it we decided it was time to overhaul it at this annual. Also all compressions at annual were 76/80 and above. Any ideas?

I am 6'5" and 250lbs and my 201 J fits me good. Helps that my wife is small and only 115lbs. We looked at it and some Beech Debonairs and surprisingly i liked the fit of the Mooneys better.

That was one of the items on our checklist for the mag. Ensuring that these clamps were on it. Thanks!

Thanks! Is this what you are talking about? http://www.aircraftspruce.com/catalog/hapages/lockwasherstars.php If so stainless or cad plated recommended for this?

Cliffy, Do you know what size or part number lock washer and nut are used for this and what the quantity is for these. I would assume that my AI that performs annual inspection would have these on hand since he works on a number of different M20J but i would like to go ahead and purchase some from Aircraft Spruce if possible just so they are on hand and i can be certain that they are used when reinstalling the dual mag. Thanks, Luke

Thanks Scott!

Good to know. Think i will stick to the 500 hour inspection. I am in the Dallas/Fort Worth area. Any reputable shops around here that you know of?

I have the Bendix Dual Magneto on my 77 201J. I have never had any issues and was wondering what is recommended for these. I can see from the logs that the mag has been visually inspected every year at annual inspection in compliance with AD 76--07-12R1 but it appears that it has been about 514 hours since the mag was last pulled and sent off for repair. Question is with no indications of any mag issues should i send this off for repair at my upcoming annual? If so what does this service usually run on price or is there a range to expect dependent on what is needed? I have heard that these mags have been phased out and that parts, repair and replacement may be hard to come by in the future. Is there any truth to that? I have also heard that these mags are junk and they really do not give you redundancy and safety of having two separate mags. Have several of these been phased out and replaced with two separate mags?

Stupid question here but to change from a standard incandescent light to an LED is it only a bulb change or is there more of a conversion required? Also does anyone know the size required for a 77' J?

I took the quiz and answered everything honestly and it suggested Mooney 201. That's what I have so I guess I'm good

Thanks for the feedback. I will get some other quotes. I guess it may be worth buying a newer model if install is going to run so high.. I am just so used to using a tablet with wingx pro it almost seems like a waste of money all together. I was hoping to get it a little more IFR friendly but not at that price.

I was curious if anyone had any price ranges for what an installation for an IFR GPS in their Mooney? I checked pricing with an avionics shop in Fort Worth and was shocked by what they were wanting. Fieldtech Avionics at Meacham was wanting $9,500 to install a King KLN90B. Does anyone have a good recommendation for avionics shop in the DFW area?

Sold!
