Yesterday I reported that I had received 2 engines, one of them being a well used Enya 19X. I completely disassembled, cleaned, and reassembled this engine. Luckily the bearings on this engine still felt pretty good. Obviously they have been changed before. The internals showed considerable run time and it had very low compression.

The parts cleaned up really well and I just ran it for the first time, much to the dismay of my neighbors.

Today I received 2 engines in the mail. One I bought and the other Balsaworkbench(Rob) bought on Ebay and had sent straight to me.

First, my engine, A very nice OS FS-48 Surpass. I purchased this engine here on RCG and thought it was a used engine, but upon arrival, I was not sure. I wanted to do a "Box to the Bench" review on it but since I could not tell that it had ever been run, I decided to open it up first for an inspection. I then ran it several times after the initial inspection. As it turns out it isn't quite as pristine as I thought. The high speed needle is bent causing some inconsistency during running and one of the pushrod tubes is dented. Overall it is an extremely nice engine and one I will keep.

The second engine is an Enya 19X. This is a very well used engine and had very little compression. I completely tore this engine down, cleaned up the parts and re-assembled it. It now has very good compression and should run quite well. I still need to clean the carburetor and get it freed up before I can run it.

A total of 4 videos were made covering these engines. They can be viewed on my YouTube channel.

I just received my latest vintage Enya from the other universe. A fellow no longer in the hobby. It is the Model 7101 60XF II Ring. The best I can find out this was released in the mid 70's. It is a very large, substantial engine. I have no current plans for this engine nor do I think I am going to rush into running it.

It felt a bit rough turning the crankshaft over and since this is a NIB engine, I knew it wasn't due to being run and just put away. It had to be the 30+ year old oil in it. So I decided to disassemble, inspect, and re-oil all moving parts.

I used the heat gun and some 3 in 1 oil to loosen up the bearings in the front housing. After that I sprayed them down with alcohol and then blew it dry with compressed air. I liberally oiled the bearings again. No they felt smoother than before. Once I do find an airplane for this engine I might just replace the bearings and start fresh. For now all internals have been wiped clean and oiled up again for storage....Continue Reading

For my nice new Enya SS25BB. What a nice looking engine. Aside from the instructions stating too lean of an initial needle valve setting, the engine starts easily and ran well for the first tank. I have two very rich tanks through it now. Here is the first.

I just scored another really nice Enya SS25BB from a great RCG member here cappy0161. Thank you Robert! This engine features a ringless cast iron piston in a steel sleeve. What that means is that this engine will last forever.

Here are the pictures.

Here is my video of the newly rebuilt Saito FA-50 in the Old School look. It is a darn nice running engine. I think I'll keep it!!

Well instead of flying tomorrow, I'll be running some engines instead. It seems like a reasonable alternative; besides true flying weather is just about to start down here anyway.

First will be my now 'Old School' Saito FA-50. A used engine I purchased a few months ago in need of bearings. I took it down again and replaced the ring. Videos can be seen on my channel, https://www.youtube.com/user/dmrcflyr2 This is now an exposed rocker engine, watch to see why.

Secondly is a NIB Enya 15 MK IV. Since I am going to fly some smaller airplanes, this engine seemed like a good buy. Due to its cast iron piston and steel liner, it should last for many years if broken in properly. I have never owned an engine this small before. It should be fun.

Lastly, a used OS 20FP that will be Volume 4 of my Box to the Bench review. Again another small 2 stroke for my foray into smaller scratch built aircraft.

Videos to be posted of all runs tomorrow. For now some pictures.

In the past I would have been buying many 4 stroke engines, but of late that has changed. I am now quite enamored with the older OS and Enya 2 stroke engines. Today I received three such engines. Yes it was like Xmas for me today and I still have one more to receive.

Yep, I'm done buying engines after that.... for this year....maybe....

Anyway to the engines. Today I got to new Enya 2 strokes from a fine fellow Aeromister. An Enya 15 IV and a new 40CX. I initially responded to a thread advertising just the 15, but as fate would have it, there were more Enya's available so I got the 40CX too.

In another thread I saw a very nice and somewhat rare OS 20FP, that Bendix1 had posted. So I picked it up too. Since this is a used engine it will be the subject of another Box to the Bench video, volume 4. Look for that this weekend. Now on to the pictures....Continue Reading
