What confuses me a bit is that the instructions say to stop the engine by fuel-cut to empty the carburator. This is not what I learned till now. I thought the rubber parts in a carburator should not be dried out and I always let fuel in the carburators of my 2-stroke engines.
Here is my theory ;
In these global warming times, the greenies forced the politicians to make petrol out of food.
Yes they did.
So now you get petrol with methanol in it. So called bio-fuel, right?
Normally, as you say, the advice is to allways keep some petrol at the bottom of the tank e.g. when in storage, to avoid the membranes in the carburator drying out.
I still do that on the Saitos.
Why? Because no one can convince me Saito has used membranes that don't like petrol.
It is the methanol they are afraid of, me thinks.
Therefore; Buy petrol without methanol, and pray the global warming scare will go away soon.

Nice Me, Horst!
Those sentences in the manual confused me too.

Regarding the drop-out when rolling;
I have a friend who has used the FG-36 for a looooong time now.It is running like clockwork for him. He runs it at 3% oil.
Yes.
I am now using 4% oil on mine, and that seems to help on the drop-out. I dont dare going down to 3%, as he so galantly does, but will fly on 4% now for a while.
Mine are incredibly easy to handstart now that the needles are correctly adjusted.
-Ignition off.
-Chole on using the thumb.
-Full throttle
-Flip until thumb gets wet
-No choke
-Ignition on
-Idle throttle
-One or two flips.
Testing it in a TF 190;

Dit you get this drop-out issue sorted out? Or are still having your engine misfiring occationally?

Artto, I was in a warbird meet 14 days ago, with the Corsair and the Tf 190. Both with FG-57.
There was no misfiring, except one of them did have a hickup in a loop..
It was very hot days, and I have opened up the H needles a bit.
Who knows how they will behave next winther.
I can live with it anyway, I love these engines. But it sure would have been nice to find out what the problem is.
Here is a note that came with an FG 33 I just aquired;
NOTICE for Gasoline containing ethanol.
"... it may cause corrosion inside the crankcase when the engine is left with no care after running ."
So, it seems it is corrosion they try us to avoid.

Yes, well, it was an answer to this question;
If it had been an OS engine, I would agree. Does Saito use stainless steel bearings?
Anyway, I avoid petrol that has ethanol added, and follow my old procedure;
Hi friends,
What confuses me a bit is that the instructions say to stop the engine by fuel-cut to empty the carburator. This is not what I learned till now. I thought the rubber parts in a carburator should not be dried out and I always let fuel in the carburators of my 2-stroke engines.

I just find it curious that Saito should suddenly be cinched over crankcase corrosion when they haven't seemed to have been as concerned W/glue fuel.
There should not be any raw fuel in the case anyway given that its a 4-stroke that doesn't draw intake through the case.

Tack ska du ha för detta..
ok back in English: Have you by ever chance measured the static thrust with your favourite prop? (22x10 I guess) In case you have a digital fish scale you might be able to do this..

I have some new info regarding petrol and Ethanol:
I did the mistake of using Shell petrol. By accident ( My wife filled the Jerry-can).
Here in Norway, Shell and Statoil puts in, I think it is 5% Ethanol, in the Petrol.
What happens with the Saitos? The run HOT, and stops. Thats right; Deadstick.
So I fill Esso here in Norway, in order to avoid this problem.

Esso 98 Octane, is what I have used.
I got trouble with 2 FG-57's and the FG-84 using Shell.
Now all 3 are running fine using Esso 98 octane.
And there is no hesitation anymore on the FG-57's, after opening up the H needles quite a bit. They are running like clocks now.
Same with the FG-84.

Ethanol alters the A/F ratio requirements. It contributes to lean conditions. Alcohol content should run cooler than straight gasoline IF the proper A/F ratio is maintained. When the engine is tuned for ethanol free gasoline, adding alcohol to the mix will lead to overheating from lean running.
Octane has little to do with it unless you are running an aggressive ignition timing setting, but your observations make sense.

When running on Shell , opening up the H needle only posponed the moment of overheating.
From 1 minute to 5 minutes.
So, you really could not save the situation by opening up the H needle. Only pospone it.
When I talk about 98 Octane Esso, it is only because then I know I avoid the alcahol. It is pure petrol.
If you fill 95 octane from Shell, you know there is alcahol there.
So; Do not get hooked up in whether it is 95 or 98 octane; That is just a simple rule to avoid alcahol.
I dont want to spend time on research on Shell and Statoils "petrol" mix;
I don't have time for such things. I want to build planes, and fly them without the engine stopping.
I just bypass the whole shabadang by going for Esso 98 Octane.
From 1 minute to 5 minutes.

I'm glad to hear your engines run well
(Wikeroy commented in youtube that his engine tends to coach when rolling the model. He said loop ws ok but he could not figure out how to tune the carb in a way the engine does not couch when flying a roll.?)
Do you fly aerobatics so how do your engines perform when flying loops or rolls, etc.?

Artto, the small hickup, or couch when rolling or looping seems to have disappeared.
I find no other explanation than the setting of the H-needle. Opened up a bit, say testing 1/4 more before flight, but then focus on how much petrol you use/how long the flight is, just to avoid emptying the tank.
I cannot explain how this remedies the situation, I just accept that it is better now, and go from there.

I ran my saito 57 ts yesterday on my 12 ft telemaster and all I can say it's the perfect combination. The plane and engine ran perfect, and I couldn't be any happier with the choice I made with this setup. it was well worth the money for the sound and the quality.

Is the engine you're talking about the newest version, FG 57TS?
I'm considering it for a BUSA Eurcoupe.
I can't speak for everyone else but yes I'm using the newest version and loving it very much. We tested how long a 24oz tank at 1/2 throttle will last, and it was an hour and 5 minutes, compare that with my os 320ff pegusas it would've burn a gallon, that's crazy. Also it sounds kinda like a Harley flying, I couldn't be any happier with my choice as it's the perfect combination for the 25pd 12ft telemaster.
