The Saito 82 would be a much more sensible long term investment than a Y-S 63

I’m looking for a prop washer and two locking nuts for my 72. I could not find it on Horizon’s site. Any help?

Gstan,

The part number for the washer, nut, and lock nut is 56135. Try a search on their site and it should come up.

ORIGINAL: w8yeWhile in the area I went to another guys house who had a old model Saito 72 that had never been run. When he started to run the engine, it seized up. When disassembled, the rod had frozen onto the crankshaft.
*Always* take the backplate off a 4-stroke engine and lube the big-end by hand if it hasn't been run in a long time. As you're already aware, it takes a little while for oil to find its way into the crankcase of a 4-stroke and that's plenty of time for the big end to sieze up if it's dry. I also do the cam and rockers with some synthetic oil while I'm at it just for good measure.

After some struggle we got the rod off the crank and naturally it was galled in the big end. I worked with the rod with clean oil and a rag putting it on the crank pin and twisting until it seemed to be free enough to run.
Sodium hydroxide (caustic soda/lye) is great for getting rid of aluminum that's galled onto steel. It disolves the aluminum but leaves the steel untouched. Of course that would require removing the crank from the motor.

I am looking to buy my first Saito for a SIG Kadet Senior ARF. I want to climb out vertical and do some slow 3D, but yet float around slow flight. I can't decide on Saito 72, 82a or 91S?

Any thoughts?

Thanks

Suitcase, your tank plumbing is perfect. Did you use regular silicone tubing on the clunk lines? I know that works good and they don't get twisted or anything. That thin, very flexible tubing that comes with the tanks looks suspicious to me and I've stayed away from it.

It's so easy to take a peek at the valves that I do it before even running the engine. I've heard of them coming too far out of adjustment right from the factory before but I don't know often that would happen.

Some folks would say to use a fuel that has a small percentage of castor in it instead of the purely synthetic that YS engines need because of the diaphram in their pump. You'd have more protection against a hot or lean run and possibly better oiling in the cam area. Personal preference though. It's interesting to go back and read Bill Robison's notes on that.

I had mentioned a few days ago that the factory tank in my RCM 40 had split and fuel was spraying into intake air and making the engine run very rich. I replaced the tank and thought there was no damage as the engine compartment appeared to be fuel proof, (not). On my third landing of the day the wood around the nose gear block gave way, it was soft and would bend like cardboard. The plane now has a new 1/4 inch ply firewall (coated with epoxy) and I used a nose gear block that is twice as long as the original. I also replaced the .56GK with a late .50. It turns a Bolly 12.5x6 at 9,600 on WildCat 15% fuel. That's plenty of power for the RCM. I fly the RCM first every year to get "current". It has flown with a Saito .40, .45, .50 and .56.

Hi Guys,

I have a few Saito engines, but I need some help with my newly acquired Saito FA-80. I am about to strip it down, clean it up and reassemble and so on using new gasket kits which I have purchased. If I did this correctly (first post!) you will see pics of the kits.

Can someone please tell me, or provide a nice exploded carby diagram so I can figure out what each of the o-rings are used for, as well as the alloy ring and a plastic looking one. I know that when I strip the engine down, I'll probably figure it out, but I'd like to know ahead of time.

Also, it looks like there are a couple of parts in the engine gasket kit which look the same as those in the carby kit (large rubber o-ring and the alloy ring).

So, hope you guys can help me!

Thanks heaps!

The white plastic washer belongs with the choke which is most likely no longer on your engine.

The metal one goes onto the intake manifold first at the head end. Then there is a black O-ring (the one in the separate package that says "Viton" on it) that goes between the metal washer and the head.

There is another black O-ring that goes inside the carburetor where the intake slides in.

There us a little fat O-ring that goes inside the needle valve body (the brass piece with the external threads).

There are two more skinny O-rings. The larger one goes behind the nut that holds the needle valve friction device on.

The smaller skinny O-ring is most likely not used on your engine but on a new engine it belongs on the front end of the cam pivot shaft.

If it were me, I wouldn't open the carburetor gasket set. All the gaskets you really need at this point are in the engine gasket set package.

You would use the cam left cam gear from a Saito 182 if that is the situation.

Generally speaking, what kind of fuel usage are people with Saito 1.80s seeing?
