I bought my first Tower Pro 46 back around 2000ish, but I had several of the sister engines, the GMS 47, prior to that. Now of late I have been selling off all non-Japanese made engines. I am primarily interested in Saito, Enya, and OS engines for their quality, reliability, and performance. But when I saw this new never run engine on eBay for $26 I knew I had to have it. That was the best $26 I have spent in a long while.

Granted it is not a Japanese made engine but having owned several before I do know they are powerful and fairly reliable. Now this one gave me a bit of trouble initially today. I could start it and it would run for about 6 seconds then die. As it turns out the low speed needle was set too lean either at the factory or by the previous owner. I am certain the engine had never been run before due to the look of the inside and smell of the engine.

Once I got the low speed needle ironed out tuning was fairly easy. Now it hand starts easily and runs quite well. I only put two tanks through it today but I would feel comfortable putting it in my Kaos as it is.

I mounted this engine to the test stand today and began shooting the video. It was shortly after the first run attempt that I relearned something about glow engines and glow plugs.

About 2 months ago I bought several sleeves of Enya #3 glow plugs. Why would I do this? Because these plugs are some of the best you can get, and unfortunately no LHS stocks them anymore. So I have to order them and I run primarily 4 stroke engines. I have read many posts and reviews stating that these plugs are great in 2 stroke engines as well. Thus far I have had the same experience until the last two OS engines.

I have used the Enya plug with great success in a Webra Speed 61, an OS 40 FP, my OS 40 FSR, etc. But this 45 FSR and my 46 SF engines simply do not like these plugs for some reason.

Now back to the original story line, running this 45 FSR engine. The engine would not hold full throttle at any richness setting of the high speed needle, nor would it idle at all. After fooling around with carb settings and the engine running poorly, I finally decided to change glow plugs. Now the Enya #3 I installed was brand new too, so I was not initially questioning the plug for the poor running results. I pulled a plug from my Enya SS40BB 2 stroke engine and installed it into this engine. Suddenly the engine would hold full throttle settings and would actually idle without dying.

I believe the plug I used was a McCoy MC-59 as I had purchased some for the few 2 stroke...Continue Reading

I just scored a really nice seemingly low time OS 45 FSR. This engine was introduced to the market in 1978 as an increased bore of the 40 FSR. I could not find a review on this engine so I have little more factual information on it. My engine is the ABC version and I opened it up as soon as I got it for my normal inspection.

The compression was excellent and the looks of the crankshaft counter weight and rear bearing show NO rust or corrosion. The bearings still feel very smooth, but I have no idea if they are the originals. Nevertheless I will not be replacing them at this time.

The top of the piston also indicates a very low run time engine. The odd thing about the 45 FSR is that I seldom see them for sale or hear anything about them, I can only assume that since it is an OS engine from the late 70's that it is a very high quality mill. On to the pictures........Continue Reading

This post shows the first run after rebuilding this engine. It really is a sweet engine. It may not be a powerhouse by today's standards or even in 1981 when it was released, but it is a very good running engine. It started on the first flip. This engine did take some considerable prime to get started even on subsequent runs I have done today.

Unfortunately, the age and low power do not make this a very attractive engine to most folks in the glow market today. Everyone seems to value absolute power now over high quality. It is my belief that the quality of this engine is unmatched. In my mind, this is an example of the pinnacle of OS quality as are all of their engines from the 80's through mid 90's.

As such it will not be sold , plus it being a gift to me, it has a bit more meaning and value.

That would be Kimchiyuk! So I have sold this member a few engines, bought a few from him, and we have corresponded several times. Well I was about to lay in my recliner and take a nap when I here the postal truck deliver the mail. I figure I better get that before I nod off. Out to the mail box I go and when I open it there is a small box! WTH? The engine I just bought from eBay could not be here yet.... What is this. I see the return address and wonder if I made a purchase I did not remember.

So I anxiously go into my room and open this package. I find a completely disassembled OS FS-40 four stroke engine! Wholly moley! I love engines, let alone totally disassembled ones! There was this note also....

In summary it stated that Dustin had been working on this engine but lost the desire to complete it. Knowing I am an avid engine lover, he sent it to me. The note went on to say and I quote, "Keep it, sell it....It's yours."

I quickly scanned the box and parts and it looked like everything was there. The caveat being the piston pin was still firmly attached to the piston. These can be quite tricky to remove. OS engines require the cylinder sleeve to be pulled out and then a hole in the casting is exposed allowing careful extraction of the piston pin. A task much easier said than done especially if the engine has sat for any time at all, or has not been run in a while.

Long story short, it took considerable oil, heat, a soak in LA's Totally...Continue Reading

Today's post is a blast from the past. I recently purchased a NIB OS 40 FSR ABC 2 stroke engine. This engine was introduced to the market in 1975 and had a production run through the early 80's. I am not entirely sure when this engine was discontinued but the SF series of engines replaced it. The 40/46 SF engine hit the market in 1987 so this engine was available up until that time at least.

The box artwork looks to be from the early 80's so I have a real classic here. Today I decided to shoot some videos of how I setup a 2 stroke engine for the first time running it. I have 4 total videos to include the first run and the third run where I begin to set the high speed needle, followed by setting the low speed needle for proper idle.

This post can also be viewed on my website along with many other instructional videos. http://www.dmrcflyr2.com/

Are you interested in glow engines? Do you have questions about operation, repair, or maintenance? Would you like someone to clean up and repair your engine for you?

Well I for one have not and will not succumb to the electric flight revolution. I am staying true to my roots in this hobby and sticking with glow power airplanes. I have a new website where the main focus is in glow engines. It is heavily video oriented because face it, most folks are visual learners.

I have a series of videos that address the most basic glow engine topics. These include bearing replacement, clean up, dis-assembly and re-assembly. I include both 2 and 4 stroke engines.

Plus for those interested in seeing a number of engines running, I have plenty of those too. So if you are into glow engines I think you will find something of interest at my site.

I am open to suggestions on content so if you need information on an issue with your engine please contact me.
