Dear All;

During my flight today, the muffler worked itself loose and fell from my plane during flight and was lost. Can anyone direct me where to order one online or any compatible brands and models of mufflers can be used for this engine. I am in Singapore and it is almost impossible to find saito parts here.

Thanks

Any of the later model Saito mufflers for the Saito 50, 56, or 62 will work on the 45

There are black powder coated brass pipes with no tank pressure
Same with muffler pressure

And then the various threaded steel / aluminum muffler assortments

The new Saito engines have this cast muffler. It will fit the 45S http://www.horizonhobby.com/Products...rodID=SAI5074D

The muffler above originally came with this steel manifold http://www.horizonhobby.com/Products...rodID=SAI5075B

There's also a 15 degree steel pipe that will work with the cast muffler http://www.horizonhobby.com/Products...rodID=SAI5075C

Hi W8ye;

Thanks. U are a very deserving moderator! I am a newbie on 4 strokes, and the Saito I had was from someone else. Without the muffler, the engine would cut at full throttle presumably from lack of tank pressure (the pressure nipple was lost together with the muffler). However, I found this nipple at the rear of the crankcase which I dun know what is it used for. If it comes out from the engine, it would have pressure. Can I tap the tank to use this pressure for constant fuel delivery and forget about the muffler?

Thanks.

NO!

This nipple is to be left open to the atmosphere or the engine will not run correctly

It is the crankcase breather

Thanks for the advise. Another question. How do I get the engine to run without quitting without having to buy a new muffler? Currently, the engine still runs but nearing WOT the engine tends to cut presumbly because of the lack of tank pressure due to no muffler. Anyway to tap pressure from the engine?

Thanks

Open the needle valve up more

Oops...I forgot to mention that the muffler dropped off but the black color steel pipe is still mounted onto the engine.

Thanks

It will not hurt anything to run the engine with just the steel pipe but you must readjust the needle valve

Hi There;

Thanks for the valuable suggestion. I'll try it out later. Howvere, by adjusting r u referring to leaning or riching the HSN, and whether do I need to adjust the LSN?

Thanks

w8ye

My Feedback: (16)

The LSN will be fine

Open up or richen the HSN

This is what I use on my Saito 45, I a very pleased with the results.
