This is copied form the Horizon Saito 1.50 specs. Crankshaft Threads:M8X1.25mm, they sent you the wrong nut.

swixtt

yeah, that's the nut they sent me.!

Ken6PPC

The M8x1.25 mm nut is the correct size for a Saito 100, 125, 150, 180, and 220.

Ask DuBro for a replacement - they sent you the wrong thread, no matter what it says on the package.

swixtt

thanks,
i'll send them an email and ask!

swixtt

well, i just fired up the 150... got it running but then i noticed it shaking more than usual. i shut it down quickly expecting to find my test mount loose... nope, it was the HEAD!! all four bolts were loose!!! geesh!!
like i mentioned before this is a new engine to me but used. now i'm really worried about it. not sure what it's been through now i probably just can't tighten those bolts??
any suggestions would be greatly appreciated in getting this aligned and running again.

Ken6PPC

Just tighten the cylinder bolts up in a cross pattern. This isn't nearly as complicated as you might think. It won't warp, if that is what you are thinking.

swixtt

OK, i'll tighten them up as per your suggestions. i'm starting about 3 turns out on the HS needle.

Looks like it works fine to me!

Love that stop-action on the prop in the 2nd photo... It almost looks as if the engine isn't running.

When I broke in my last Saito, my wife asked me not to get oil all over the picnic table, so I put a hunk of fuel tubing down to an old fuel tank and caught the crankcase oil breather oil in there.. It was quite a bit, as I remember...

Bru Line makes a good filter. It is worth the investment of time and money for the inverted Saito carb. Your challenge will be to get it on the stack with the engine mounted on your plane. You may need to take off the engine. I have been using these filters for 20 years on my two cycle engines and they were a challenge to get on the carb but once on, they stayed there. As a precaution, I use a small wire tie to secure the filter body to the stack.

After I wrote you, I flew my new Saito again. Used another gallon of fuel and adjusted the low side again , turning it in another 1-1/2 turns. Since I first flew the plane, I estimate that I turned the setting inward at least four turns. One thing you wil notice when the needle is adjusted properly is that un-burned fuel will not be discharged from the muffler exhaust which will save you money. The factory ships those engines with that needle wide open. Now my engine runs really well. Good luck with it!

Capt Lou,

Looking at the Bru Line filter for the first time still in the package it's hard to believe it would stretch as much as it does. It is a challange getting it on the Velocity stack. It's also a fair challange getting the filter disk in the filter body but makes a nice installation when it all comes together. I already had the carb and manifold off the engine and I do believe that helps. Speaking of the manifold I was supprised to not find any gaskets or anything in the joint between the cylander and the manifold nut. Or maybe it's still in the cylander and I just can't see it. (actually haven't looked really close yet) This is a new engine to me so I don't know much about it yet.

Well it seems to be running pretty good now i richened it a little and turned the LSNV in about 1 turn Smokes a little and is peaking 9350rpm full throttle and i can get it to idel down to 1300rpm then rapidly accelerate it back up to peak with out hesitation. 1300 RPm is bairly running i definetl wont have it set up like that in the plane i think minum will be 2000 rpm for idel on the plane.

Bob
Sounds like a good idea i just put a little fuel tubing on the nipple to keep the oil off the engine mount itself it started to fill up with Oil. but the table and the block of wood is saturated from oil from all the engines i have ran on it. coffee table was left buy my ex-wife she was always complaining about anyone setting anything on it. Its the perfect size for my Test stand. [sm=lol.gif]

Gonna have to modify my test stand so i can run various types of engines on it the throttle control should be able to move to one side or the other depending on the location of the throttle leaver on the engine has to desighn some sort of track system so it can be moved from the left to the right.[sm=idea.gif]

Ron:

The Bru line body does strectch. Use a larger flat screwdriver to stretch it or any other similar device that will expand it. Also, try putting a little oil on it so the rubber surface doesn't interfere with sliding it on the stack. Use oil also on the opening for the filter disc to help get the disc set. I understand what you are experiencing but they do go on. Over time, the lubricating oil from your burnt fuel will get on the Bru line body and make the rubber more pliable and easier to use.

Capt Lou,

I got the filter on. Thanks for all the help and suggestions. I appreciate it. Have a great day.

Test005

Broke in my FA82 tonight, ran it with 14x4w, Saito plug and 15% Byron fuel synth/cast. mix.
Fired up right away and ran 2 tanks really rich at about 4-5k rpm. Ran a third tank on a bit more rpm, still very rich... Finished with two tanks heat cycling, by leaning and richening the needle at full throttle (this is how I do with OS 4-s so I figured, why not? )

Well, nothing to report really... It runs perfectly and is now installed in my Sig Somethin' Extra that I hopefully maiden on Sunday
Seems like a good engine to me.

Sounds good, enjoy flying Sunday

Ken6PPC

You may have already done this, but just in case.... Don't forget to lean the LSNV!

Saitos come from the factory set REALLY rich on the low speed, and will never perform up to their capacity if it isn't set properly.

Test005

Thanks guys, I'm aware of the Saito lsnv default and will adjust it accordingly. I didn't bother much with it during break-in though.
Come Sunday I will peak the engine out and then back off a healthy bit to keep it rich and nice for the first couple of gallons. I will also adjust lsnv as she breaks in more.
Did I say this already, "Seem like a good engine to me"?.

Ken6PPC

Yep, I love my 82's. All three of 'em!

Question for the Saito Gurus. I just traded for a crashed Saito 180 with some carb damage. Which direction does the spring behind carb go? I took a 180 carb apart to replace broken needle valve and the spring came out with wide part to the rear of the carb and the narrow part to the carb barrel. I tried to reassembel but the spring narrow end would go in the hole for spraybar and prevent barrel from fully going into carb body. There is also a thin thrust washer that I placed agains the rear of carb body. I tried to view these parts on parts breakdown on web but the parts are vague and not visible. The spring with wide side to the carb barrel seems to work good but want to get your opinion, advice. I will fire this ole Saito 180 off tomorrow afternoon. The engine is one of the older ones but seems to be in topnotch contition as far as operation condition goes If you know of better view of parts breakdown on internet please let me know. I read one of Bill Robersons old post about the 180 carb and o-ring just recently. The older 180s don't use the small o-ring that comes in the rebuild kit.

Hi Guys,
First of all, great forum, it's a goldmine for information and 'how to's'.

I have a couple of questions, if any one could help,

1. The Saito FA-65 in the photo, what version is it?
2. The needle assebly is bend, where can I get parts. ( I looked at the horizonhobby site, but don't know which is the right part)
3. Will the new FA-65 Carburetor fit this motor?

Thanks!
Ronnie
