I didn't try that, and I have since sold the engine, there is a video somewhere on RCU of it running. I remember that I deliberately set the LS needle a little rich so the engine was a little raggedy at idle. I'll have another some day.

I always ran a 14 X 6 on my 80. It didn't set the world on fire. Mine wasn't high compression. I think I should have been using a 13 X 7? The guy that owns it now is one of BLW's friends and he runs a 13 X 6 on it. One of those gray Graupner ones from Hobby Lobby.
Jim, if I remember correctly he is using that 80 on a Jungmeister kit, and it flies with attitude. I never checked his prop. It seems to have plenty of grunt just from watching him fly it.

Remember the crazy guy in our club who threatened to use his gun on one of us? (not mentioning any names) Didn't he have an 80 on his Flying King? I was a little impressed with that engine. I was going to tune it one day and the entire nose section of the plane flexed about 10 degrees when he gave it throttle. It returned when he went to idle. Crash damage. I don't think he ever ran the engine again after that. I told him to shut it down and I got away from it. I thought it would pull the nose off at any second. We never knew exactly how many times he had repaired it from numerous crashes.

Hi guys a question about throttle barrel springs and a caution too.Can you make your own throttle barrel springs or do you need to buy the saito set? and the caution is never enjoy a handrolled cuban seegar before stripping your 82b carby,you all knew that did'nt you?

Hey OF, I figured that the ashes would make a great polishing agent for the carby, or is that not what happened???

I guess it's been too many years for I cannot remember if that little guy had a 80 or 91 in that flying king? It must have been 2004 the last we saw it? The Flying King had plenty of power I remember. It must have been his Kadet Sr that had the 91?

Glenn has two 80's. the silver one that you put new bearings in in 2007. It is one he must have bought from Steve around 2003 and then he has a 80 Golden Knight that he got from me a couple yrs ago to replace his 65 that he run with the bad bearings until it wouldn't run any more. Steve would't fix the 65. Glenn still has it in a box in the corner of his shop if you want to fix it but the engine will need a piston and ring as well as bearings and cam followers. Glenn also has a silver 91. He also has a OS 91 Surpass I and a ASP 91 FS.

Does anyone know if you can modify a commonly found spring out of something else? and i forgot to ask why it's there in the first place as there is already a machined groove in the barrel,do you have to run a spring?

In all of the Saito glow engines except the 125, there is slop in the groove in the throttle barrel to prevent binding.

The spring keep the slack out of the throttle in-out movement.

Without the spring, your mixture will vary and be very noticeable around idle speed.

If you are good at winding springs, you could just copy one from your other Saito engine.

Some people in these forums have amazing skills

I bought a couple used Saitos that someone had lost the spring. I never tried running one that originally had a spring without one because I know what happens when you push in on the barrel and they go lean.

Fuel, while lving in Malaysia I had a lot of trouble getting my Saito 50 to run until I stripped the carby and found lots of cellulose like substance in the needle area.  Once cleaned the engine ran like it should with new fuel until the new bottle was 1/2 full then same problem.  At the suggestion of a european local I froze the fuel and found a block of wattery substance forming decanted the "fuel" from on top of it and used it in a 2 stroke glo to great effect.  Then glutton for punishment that I am I got a litre of "home brew" fuel and left it open on the floor of the hanger at MAS for an hour.  The result was on a 90% humidity level evening the fuel increased in weight 10% which I found unbelievable, so I repeated the experiment the next night with Byron fuel.  Same result, so I froze both did the decant thing and got almost the same result in reverse.
The upshot of all of this was that I now use "closed loop" refuelling in tropical environments.  The closed loop thing means that my fuel is transferred from a bottled that is sealed apart from 'fittings" into the fuel tank via a pump and any overflow goes into a sealed overflow bottle for later reuse.  Works for me and I also keep all my fuels in a dark place (shared with the possoms and pythons I think) at the back of the shed.  I don't know about nitro (though you are probably right) but ether doesn't like sunlight
Lastly I always use "fresh / new" fuel for competitions for all the about reasons (contamination) with the left overs used for testing and sport flying

And approx. when it was made.

I just put fresh bearings in it and its smooth as glass.

Charlie, this a high compression one it is virtually identical to yours. I repainted the engine about two years ago. It looked much like yours before that.

I thought that the GK version came out quite a while after the regular FA-80's. So they are likely a lower compression as so many people were having trouble with them. I an pretty sure that mine is a high compression version but it is a plain aluminum finish engine one of the early ones. I remember getting it as soon as they became available.

There would have to be a "A" or "B" on the right engine mounting lug for it to be high compression

Jim, neither of my .80s nor the 1.50S have a letter on the lug. I don't know what that means if anything. That silver .80 I got in a trade in exchange for an Enya .90 fourstroke.My Saito collection is in pretty sad shape now at, a .30, .40a, FA .40, a .62, two .80s and a 1.50S.
