RE: Welcome to Club SAITO !
Hello all. I'm trying to find a carb for a saito 90T MKll twin. It was my friends engine. He passed away a couple of years ago. I want to get a couple of his planes back in the air in memory of him and I need a carb for this Saito twin. Thanks any help would be appreciated.

Is yours the 90 TS or early 90 twin? If 90TS here's your carb

Woops, sorry it won't let you cut and paste the parts links. Go to the link and then parts.

I have the older dual carb style 90T. The intakes headersare differenent then the 90TS. This carb mounts on top inline with the cylinders. I found a carb for the 100T. The carb on the 100T looks like it might work? Any suggestions?

To expand on my story a bit, I had bought a 2-1/4" standard aluminum spinner to fit over a 14x6 prop. The standard spinner depth wasn't enough to allow me to use the nut, jam nut, drive washer, etc. That's why I had to go to the Ultimate style - for the added depth for that hardware.
Again, just my $.02

I'm surprised that you had to use two washers. What size prop are you running? It sounds like a narrow pitch. Just curious (or is that nosey?? )

Hi, I broke the carb mount off my 25 year old Saito FA-45 MKII which has been in storage for 25 years. Where, if anywhere can I get a new rear cover with the carb mount? I tried what I could with JB weld while knowing that wouldn't work. The gasket is exposed with how it broke, so I can't just rig something to hold the carb. I'm going to need a while new rear cover.
Thanks,
Dave

I've never actually seen a Saito 90 single crank pin engine but I happen to own a 100T single crank pin, 60T double crank pin, and a 90TS double crank pin opposed twins..
My 100T looks like the one in the picture but I have no clue about the commonality of the carb with the 90T

w8ye, could I get the measurementsbetween themounting bolts on your 100T carband the distance from the intake inlet centerlineon cylinder to the carb flange if its not too much trouble. Thanks

The three cylinders are still on my three 125A's.
If I could sell them I would put the new type cylinders on these engines.
The original 125 cylinder is bad about breaking out the exhaust threads if you crash. That was the reason for the new cylinder on the 125 that I played with last Christmas. I tried to trade the owner out of it but I was unsuccessful.

I resurrected my Carl Goldberg Tiger 120 project, I had mounted my Saito 1.30 twin, hence the absence of cowl cheeks. Then I sold the 1.30 so my old High Compression Saito 1.50 is the engine of choice now. I hadn't flown the 1.50 for about 3 years so I unboxed it and there it is. There is a Perry vibrator pump hidden below the carb and it actually works. I'll show the finished product in a couple of days.

-How/why did you get the intake manifold to go straight back?
-How can you tell if you have the older high compression version (other than having a new one and feel the difference?)
I have a 1.8 I bought used and the compression feels high, but I don't have a new one to compare to.

My daughter bought that for me for Christmas in either 1991 or 92, it is one of the first 1.50s sold. The compression ratio is either 14.4 to 1 or 15.6 to 1. Saito lowered the CR when too many whined about it being demanding about how you start it. It runs the same on 5% nitro as it does on 20/20. I have an .80 like that too. Neither has a model designation on the right lug. I moved the carb just to see what would happen since the 3.00's cylinders have the carb on the intake port. The 3.00's carb mount would not fit the 1.50 cylinder so I just hacked the elbow out of the old intake pipe and pressed what was left back together in a vice. It didn't change the performnce by a single rpm. It's kinda novel that way so I just kept it as is. Saito changed the CR to about 12.92 to 1 at some point. When the early .80 came there out was a story circulated that when Saito built the .80 they didn't change the combustion chamber volume from the .65. Whether that story has any credibility or not I don't know. The best way to start this one is to use a starter without priming it first and after a few revolutions it will simply begin to idle. Although I've got pretty good at priming it lightly and it will start on one backflip.

Ok have a friend with saito 91, he say it makes power but wont idle, hes got it mounted on a test stand, when you remove the glow starter it quits, its got a brand new OS FS plug, I told him to bring it to me so I could take a look at it, any of you saito guys come across something like this, I would appreciate some advice before I dig to deep into it

But also if the engine has been used a lot, it could be low compression causing it. if the compression ratio gets below a certain level then the engine has trouble idling without a assist on the glow plug. sometimes running a higher nitro ratio glow fuel alleviates the problem. But then one needs to check to see if the valves are leaking or if the piston ring is worn or both.

RE: Welcome to Club SAITO !
How does the straight-in intake manifold affect the fuel tank placement if you are not using a pump/regulator? Seems only a horizontal engine mounting would work with that intake approach? I am curious as I have an application for my Saito 180 that could use the straight intake to great advantage. Thanks.

RE: Welcome to Club SAITO !
I'll try to answer everybody, Richard, I actually mounted the engine on its side first but the throttle was a problem so I experimented and found the the same bolt holes fit the GP mount in the upright position. The carb was on the centerlione of the tank when layed down. I simply cut the elbow out of the stock intake pipe and pressed what was left together with a vice. OF, the straight in carb mount did nothing for the performance. It just looks cool.
