RE: Welcome to Club SAITO !
The fitting on the back of the engine is for crankcase venting.
Attach a short peice of fuel line to it (approx 4 inch) and leave it open.
Excess oil burps out that line. It doesnt connect to anything. Just make sure it goes somewhere
outside the aircraft
Disaster averted

RE: Welcome to Club SAITO !
Hello All
This is my first post to this forum. I am wondering if anybody can direct me to a location where I might find an owners manual for a Saito FA-65. Ijust bought it used at an auction and it is barely broken in. But, I am really excited about mounting it to a GP Sporster that I have and want to dial it in. Thanks for your help.

I bought my .65 almost 20 years ago. WOW what a sweet engine. It now needs a rebuild. I think just the two main bearings and a new ring should do it. I have never had it apart. I now wish I had bought at least 3 of them. Would be fantastic in a twin. Super reliable.

Jafo150, that's the prop nut and second locking nut. You will see where the locking nut fits. Since 4 strokes can backfire and throw props, the locking nut is often used.

Thanks but, without a better description I cant really tell. I might guess but i might guess wrong as all my exp is with 2 strokes. What about the little coned shaped nut with threads. what about the big washer,? does that take the place of the thrust washer? you can see my confusion i hope.
thanks again</p>

The engine was purchased on E bay about two years ago with a bent crank shaft which was replaced along with a carburetor upgrade kit. Since then she ran beautifully would start with no problem, my best behaved engine. Last week she just would not start. Changed the plug, checked the push rods, checked the fuel and nothing would get it to start. I decided to take apart the carburetor and clean it in case there was some dirt clogging up something. And to my surprise as I took it apart i found the ventury on the high speed jet had a crack in it. I also noticed that the jet it self had becomes pitted. I have ordered replacement parts but wonder if anyone knows how this could happen.</div><span class="Apple-style-span" style="font-family: Arial; ">Kevin</span>

That slot is where the fuel enters the airstream. Here is a shot of the one in a 2.20, a sleeve slides in and out over the slot metering the fuel from idle to about 85% throttle. A flat ended rod inside the spraybar serves the same purpose in a SuperTigre carb. The slot is generally referred to as a "cats eye"

RE: Welcome to Club SAITO !
You learn somethjing new every day. Is the split meant to face looking out or looking in towards the cylinder? Or does it matter?

RE: Welcome to Club SAITO !
Yes it is common for the spray bar to have a slot cut in it like that. Most of the time it looks like a elongated diamond shape and not rounded like that one on yours. The pit on the end of the needle was there since day one. But the sensitive part is more towards the shoulder so it probably worked fine for you. Normally the split faces straight down from the top, so it points down. But with the Saito engines, the bottom of the carb is up, so you want to facing straight down towards the bottom of the carb, which would have it point straight into the intake manifold tube.
I would check the O-ring seals on the intake manifold and make sure the valve gaps are set OK. If the compression feels Ok, it may simply be a bad glow plug. I had a glow plug fail on my Saito 80 once. It would light up and glow nicely but the engine would not fire at all. i put in a new glow plug and it fired right up and ran fine. Sometimes the glow plug element gets too contaminated and it doesn't initiate the catalyst reaction that lets the engine run.

Here is a diagram from the manual. This is how it fits on the crankshaft. One side of the nut labeled #28 has a machined groove for the 'cone' section of #110. This is easy to reverse if you aren't paying attention.

I have no idea about the crankcase, but you can tell the difference by the pictures.

There's nothing wrong with either crankcase.
It is just the old "A" version and the new "B" version
They redesigned the engine for the FG-14 and then they went back and changed the Saito 72 and 82 to be like the gas engine.
The cylinder and all the moving parts are the same in both versions

I have two of these engines, one GK and the other the regular color, both are great. The GK more than 3 years, and the other almost two, they run flawless.

I am not a Saito expert, but I never heard of the Saito .82 having a crankcase problem in its original form. I suspect that the introduction of the B model has more to do with the introduction of the 14 cc gas/spark version. Why make two different crankcases when one will work for both versions? Just my $.02 worth.
