Hi,
I am getting back into flying airplanes this summer and plan to start up some of my old engines, I know engines and how to tun and maintain them. But I have never taken one out of storage and ran them again. Most have been oiled and stored in zip lock back, but some are still on the airplanes I flew them on. I don't want to damage good emgines if I can keep from it.
Thanks for any info you can give me.

Hey Lwgreen where do you fly. I am not to far from you.

Well... Im no expert, new myself. However, my Plane has an OS .46 FX on it. After much frustration my first go at this hobby I put afterrun in it, (Marvel actually) and hung it up for 4-5+ years with absolutely no other maintenance. Perhaps I got lucky but the only thing I did when I started back into the hobby was to tear the motor down and clean all parts with Alchohol, then oiled it up real well and reassembled it. My current instructor was able to start it right up and made almost no adjustments to the tuning to get it to run like an OS should run..

Hi
We may belong to the same club...... how you doing????? I am looking at my engines and want to get a couple out and start them up. I wanted to make sure the one I am putting on the new plane will run. I have a 4c to put on the new cub and it needs checked out also.

Glad to hear you had good luck with this, I have always put marvel air tool oil in my motors. I plan to oil them with marvel and let them set with some fliping the props from time to time to get oil worked into everything. My engines have sit longer than that, just hope I don't lose any, I like to take care of my stuff but I feel I should have oiled the from time to time.

Not to worry!

I just went through the same thing last month.....starting after 5 years as hanger queens.

They all started fine with a little prime. Needles were quite close to what they were 5 years ago.

The JETT engine was a little hard to turn over (takes a prop-pitch rotor!), but it finally started and one of the Enyas threw a prop because I over-primed.

One of the other Enyas had metal oxidation issues in the carb throttle body, but some 0000 steel wool took care of that.

I understand exactly how you feel, but I'll bet you will be pleasantly surprised!


And they all started!

I will be starting a couple up in the next couple of weeks, I will let you know.
thanks

If they were stored properly, your good to go........

I went thru this last year. I added some after run oil to the engine and hand proped it over to see how it felt. Then removed the glow plug and added more after run and purged all of the old storage oil out. I then made sure that all the oil was out by turning them over with the starter. With fresh oil in I connected the fuel and started the engine.

One engine was a little stiff.... I had been breaking it in with a 50/50 mix of castor and syn...after adding the air tool oil and motoring it over with an electric starter it was much looser. And after running it, it was normal again...

Personally id remove the backplate let the old oil poor out double check everything looks good ie no rust on the bearings or anything, than id trow some air tool oil in the bearings both ends of the connecting rods and a bit down the glow plug whole to get the cylinder / sleeve or cylinder and ring depending on what kind of engine...
