In the last 3 years I have owned 6 of these engines. Much of what I love to do in this hobby is to buy and sell engines. Sometimes if I get one in less than pristine condition I may sell it to 'trade up' to a nicer newer engine. That is the case with this engine. The FS-90 I just had was complete but the outer case was tarnished and not as pristine looking. Well when I found this gem on RCG I knew I needed to have it.

So here is my 6th OS FS-90 engine and a video of the third run. It is so new I need to break it in, so there really aren't any peak readings.

Just another typical Enya 4 stroke engine.

I have found several good deals on eBay in the last month, I really don't even shop the classifieds here anymore. Plus I like to do rebuilds and eBay is full of those type engines. The balancing act is if I plan on reselling, I have to get the engine at the right price to buy the parts it needs and still at least break even.

The engine featured here is NOT one that I can flip and make money on, but I will fly the crap out of. As with so many engines on eBay, no one can really trust the seller to know what they have or are talking about. Thus these are higher risk buys.

My latest is an Enya 46-4C. The box and paperwork say it is a MKII. It is in decent shape overall. It does have a broken fin on the head and the throttle arm is broken off. One of the reasons I took a chance on this engine is that I have some spare parts for it since I have had several of these.

I estimate about 1 gallon of fuel through it based on the carbon build up on the exhaust stem and piston. The bearings could still be used once oiled up but could be replaced now too. the truly unfortunate thing is the crankcase has some strange damage on the housing where the timing gear shaft bearing fits. I am not sure if it lost a bearing or if someone really damaged it trying to get this bearing out. Either way the bearing came out on the shaft. I am not sure if I can get anything in there to dress that area up or not. If I have to buy a new crankcase all bets are off of ever reselling this...Continue Reading

I'm a sucker for Enya 4C engines and when I found a listing on RCU for an 80-4C I watched it carefully. For a few days I watched and pondered,; the asking price was a bit high for what it was. After about 3-4 days I submitted an offer for $30 less than asking price. Well, it was accepted. There was only 1 picture to look at in the ad so it was a bit of a gamble.

I should have known better, as I have owned enough Enya engines, they are pretty indestructible. It arrived a few days ago and I took some pictures of it. Unfortunately I am at work entering this post and I do not have the pictures on hand, but I will post them tonight.

It was pretty dirty on the outside and was quite hard to turn over. The carb had some damage and dings. it was also pretty badly tarnished. I completely tore the engine down and was happy to see that the top of the piston was not dark at all. After removing the exhaust valve I found that this was a fairly low time engine as there was no significant deposits on the shaft. The piston ring was free and rotated easily with little to no deposits in the ring groove.

Aside from the carb damage and a ding to the intake manifold it looked pretty decent. I ordered a set of crankshaft bearings but after cleaning the residue off the rear bearing I decided to just re-install them and see how it runs. It runs pretty darn nice as the video shows. This is an engine I will be keeping for myself.
