There's an "O" ring there. In fact, when I opened a gasket kit for my FA91S the "O" ring for the top of the manifold where it enters the head was in a separte bag & marked "Viton/high temperature".

We use coolpower here in Oz in vintagents and no one complains, me I haven't had any probs, likewise both SIG and Byron fuels which I used in Malaysia and the various clones (factory mix) here in OZ.  Correct viscosity for the application is more important than brand names me thinks and now back to the castor press for some oil for the diesels

The upper Viton O-ring goes right behind the black washer, its silver on yours and black on the .62. The .40a has a seal unique to itself.

Well I'm glad you took the time to read (and understand) my post in it's entirety & didn't jump on the anti Cool Power bandwagon.

5 stars for that.

SBD, one other thought, when installing the intake pipe, place the upper O-ring in the indentation that is machined for it, then push the pipe through the O-ring. You'll never get the O-ring into place with the pipe in it.

Very nice Dr. now all you need is a TurboHeader with its 90 degree adapter to compact that exhaust.

hmm, dont know what that is, i will look it up, is it something for sound purpose, or for performance or for aesthetics?

Hobbsy

My Feedback: (102)

It is a compact tuned chamber that on all but the 1.25 enhances the performance by 210 to 300 rpm depending on which Saito. The have a cool sound and are easy to hide. RCSpecialties is a sponsor here and here is one a Saito .62, as you can see it could be pointed several directions. THis other on e is on an old Saito FA .40 and an ACE 4-40. A work in progress, slow.

A couple of Harley's were mentioned so here's my chance..... to show you my latest fine art Harley photograph! I do a lot of photography and when I went to the national drag races last weekend I actually spent more time in the motorcycle parking lot than near the drag strip.

In this picture you see a Sullivan Soft Mount, it was a short lived brain storm. I thought because the FA .40 was so smooth running I could use the soft mount, no way. As Harry Lagman used to say, "that thing shook like a dog passing a peach pit" tortional impulses of course. It now sits in Hangar 9 nylon mounts.

Thanks for the o-ring help..... one question though,the metal ring on the intake tube is loose.... its off the tube now i do have it... is it suppose to be loose or do i have a issue with the intake tube?????...THANKS AGAIN

My Feedback: (102)

Just so it won't slide over these three little bumps or raised portion of the pipe which ever yours has.

I started bashing a mostly built Sig Somethin Extra for a Saito 72 that needs a home. Somebody gave the kit to me. Took a small hammer and knocked out the firewall and oversized servo tray. I am lengthening the nose by an inch and adding at least another 2 inches on the tail. I will remake the rudder and elevators with counterbalances. I also cut down the front fuselage top for a hatch from the firewall back to the turtledeck. I need to raise the engine as much as possible to make room for a 13x6 APC.

I final got my Saito 120 fixed. The problem turned out to be the new bearing I purchased. I got another new stock Saito bearing from Horizon and installed it and the engine is a smooth as can be. I put it back in the plane and flew it last night. The engine ran good and had better power and did not leak any fuel.

just came back from the maiden flight.  flew the revolver with the saito 125, using 15% nitro with synthetic 18%.  the first flight, about 4 minutes into flight, the engine turned off.  the baby can glide, landed it great, dead stick, brought it back, and turned it on again, then i tried to tune it, i turned needle in 3/4 turn, then engine began to decrease rpm, so then from that point, i was able to turn needle out 1/2 turn, and then, it had great throttle response, and i flew her again.  by 4 minutes into flight, engine began to lose power, so i landed it again.  i then flew my GP yak, with an os 3500 and perry pump,  flew her three times.  don't know what is up with the saito.  the glow plug is brand new, and it is saito plug.  the engine has now had about 5 tanks of fuel flow thru.

It is going lean as the tank empties, set the HS needle about 300 rpm rich of peak rpm or better yet about 150rpm rich of peak with the tank half empty.

hi, thanks Hobbsy, however, tank was 2/3 full when it landed. do you think maybe it still needs to be broken in, or maybe, it is overheating? the temp was 99 and i am 70 feet above sea level, and wind was 8 mph today. how do you feel about using a perry pump?

Hobbsy

My Feedback: (102)

I personally am not a fan of Perry pumps but others love them. I am a fan of the Cline regulator which will let your enginj run exactly the same from full tank to empty no matter where you put the tank. In fact it will save you some fuel as you won't have to run it so rich at the beginning of the flight. Uh oh, I'm spending your money for you again. Others will agree that the Cline regulator or the IronBay are great remedies for poor tank position.
