My problem is I can't get to the low speed needle without pulling the engine about an inch off the firewall. So, I can't do it while it's running. That's one thing.

Does anyone know if there is an ideal angle that a muffler should be mounted on a four stroke in order to keep it from loosening?

Bob,

It shouldn't matter. If you keep having problems you could try virgin teflon tape.

No, I'm not but a friend of mine is. I thought I read somewhere that a specific angle was called for.

Thinking about it, there was some discussion at one time about this.

The summation of the discussion was that the muffler should be kept as close to the crankshaft center line as posssible to keep the effects of the vibration to a minimum.

In other words, don't put an eight inch extension on it.

Teflon tape is not used by enough saito owners. It's so wonderful.

BLW did suggest using virgin teflon tape back on 17 Nov. But, how do you find anything VIRGIN in todays world? Except Virgin Olive Oil, that is.

Re mufflers, with extensions depends on what sort, flexible is ok if mufler is secured elsewhere, I have never really had a problem with vibration no matter what angle the muffler was installed at.  Never used teflon tape found it makes a mess when subjected to heat instead if I had a muffler working loose all the time (no matter what the engine or type) I used a Locktitie compound (forgot the number)  to "lock the threads on the locking nut (which is done up tight of course) always worked for me
Two things to note, most places that sell Locktite have a book of recommendations use that (thread lock is the thing I use) and buy a bottle of release agent at the same time saves time later if the nut proves difficult to get off.

OK....I have to jump in on this again. I have only used Saito and O.S. four stroke engines in all my models. Never had a muffler or extension come loose. I always clean the threads (all threads, inside and out) with any good cleaner. Then apply a small amount of regular motor oil. Lock everything down real tight and then run the engine. Make sure the prop and spinner are balanced and only use a metal motor mount. Get rid of the black plastic ones away. Run the engine through a full tank of fuel and then let everything cool down. This has work for me going on 20 years now.

My first Saito engine.......40A

After all these years I finally broke down and bought one.

I want to use it in one of the Blk/Org Nitro Planes Senorita's. http://www.nitroplanes.com/90a268.html

I liked the two needle carburetor and figured it wouldn't load up at low throttle settings.....

Wish me luck!

Do I get a number now?........[sm=thumbup.gif]

You don't need any luck. It will run perfect any way. You will just love it.

If it works well in this EP model I might have to expore some other Electric to Glow conversions...

You'll learn all about electric-to-glow conversions with that motor. It's a shame that there's very few Glow planes being made in the .25 size anymore.

The .40a High Speed needle is pretty sensitive at peak. 2 clicks is a big difference. I love my .40a.

As I have stated before, I have had no difficulty with air bleed carbs stuttering, etc., when adjusted properly and running good fuel and good glow plug. My FS-40s run just fine with airbleed carbs.

This is in reference to Broken Wings comment about Saito's two needle carbs versus other engines air bleed carbs. I do agree that the Saito two needle carbs are a bit better than most air bleed carbs, but not by a tremendous amount. He may disagree, of course.

Three strikes, that is why my 100 vibrates so much:
Black plastic mount, extension on the mufler and is not angled in line with the crankshaft centerline.
It vibrates so much that on the maiden flight it lost 3 of the mount screws. Thankfully it went dead stick and I landed.
The mufler also became loose due to the vibration.[X(]
That is why I check this forum often, there are a lot of good valuable info here.

The Saito 30's have airbleed carbs but they are easy to needle and run very strong.

Of course, the Saito 120ABC had an air bleed carb that was superior to the later, less expensive to produce, TN carb. That early Saito air bleed carb was not quite like the more typical air bleed carb we see today. See Bill Robison's notes for details.

I think that early Saito 120 carb was too expensive to make?

Yes, that is my understanding. Thanks. I have a 120ABC in really good condition and the carb is a jewel.
