I have a Magnum FS 120. I wanted to mount it inverted with a slimeline pitts muffler. However, Slimeline doesn’t make muffler for Magnum. They make an inverted pitts muffler for the OS 120. I understand the Magnum is a knock-off OS. Will this intended OS muffler work on my Magnum? Thanks in advance for your input. I wrote and called Slimeline but no answer. Seems like they are very busy.

You will have to call them. The 108 is not currently being sold.
The ASP 108 is the same engine and a source would be
www.justengines.unseen.org
They are in Britain and you communication would be cheaper over the net but shipp ing is about as fast as from Hobby People

Most 40/46 magnum and OS mufflers are interchangeable as long as you stay away from the OS FP and LA series

The latter two engines share the same mounting dimensions as the OS.32F/SX engines. I'm sure Jim knows this, but some of you may not.

RE: Magnum Engines?
i just bought a magnum xls46 and haven't run it yet. how did you seal the carb in case i have problems and it came with the remote to put the needle valve to the back of the engine. some say putting the needle valve to the back of the engine works fine and others say leave it right on the carb. thanks for your help.

RE: Magnum Engines?
Using an adjustable wrench, carefully loosen and remove the plug from the side of the carburetor.
Carefully loosen and remove the needle valve assembly (including the clear gaskets) from the rear
needle valve mount. Carefully thread the needle valve assembly (with the clear gaskets in place)
into the side of the carburetor and tighten it securely using an adjustable wrench.

I would leave it up front, once you set it ,it stays pretty accurate for a while unless you change fuels or something to up set the fuel flow, youll be looking for a leak if you change it to the rear.

RE: Magnum Engines?
I just installed a magnum 91 rfs in a tiger 60, which had a thunder tiger 91 in it for many years.(bearing finally gave out in the tt) I have used 14 6 prop in both. The TT was very reliable, the magnum runs great and seems to have a little more power (although it is much newer) So far, have had to fix a leaky needle valve with a new o ring (home made with silicon fuel tubing). otherwise, these two engines seem to be pretty equal.

RE: Magnum Engines?
I am having a problem with my .91 2 stroke magnum. It runs great at the start and then it heats up to about 250 degrees. i cant dial the mixture down any more or it runs too rich. the engine stalls at idle and when i try to re-start it, it feels like it has less compression. any ideas...i have a few but want to hear from others?

[:@] PURCHASED 2 MAGNUM 30 FOUR STROKS AND DURING THE BREAK IN, ONE OF THE TWO STARTED TO SQUEEK. SHORTLY AFTER THAT THE DOG GONE ENGINE BLEW UP. THE CAM BEARING CAME APART AND DESTROYED THE ENGINE ON IT'S SECOND TANK OF FUEL.
I RETURNED BOTH ENGINES BEING THEY WERE GOING ON A TWIN ENGINE PLANE AND BOUGHT OS ENGINES. A BRAND YOU CAN TRUST.

Not always, that`s for sure
You are new here, but in time you will see that there`s no guarantee for success just because you buy OS. Their ringed engines are still good, and the fourstrokes apart from the Ultimate 70 and FL 70 are also good.

RE: Magnum Engines?
The magnum .52 XLSis a beauty. My friend has one on a Rc airboat with a APC 11x8 pusher and it is awsome. No problems at all, i actually just bought a Magnum .46 XLS off of him for 50 bucks and the only thing he did was break it in, im just wating to get a prop, then im starting construction on a rc airboat. Any body got a 10x8 pusher prop they dont want?

RE: Magnum Engines?
Hey Ed - do you have a Magnum 120RFS? I have one new in the box and am wondering how they perform.
I have a UCD 60 that I have to choose between the 120 and a 91RFS. I'm leaning heavily toward the 91 just because of the warnings from GP and the weight of the 120 but...

I had several of those over the years. They were unspectacular in power, but held up well otherwise. I never rely on Magnum four-strokes for high end performance. You have to pay lots more to get that in an engine. However, their two-stroke .52 bluehead is a real screamer, for the price.
I get confused with the Magnum lettering system for identifying models of their engines, so get a good laugh out of my mistake if I have made one. I would have...

RE: Magnum Engines?
dang, Magnum guys, I broke a Valve Spring on my Son's Mag 180 4st 
,,, heehee but this gives me a great opportunity to remove one of the Head Shims for 15% [8D],,
so I was doing a very slow and tight right hand circle with using the rudder (Cermark Edge), and as it came around to down wind the Tail Wings stalled and the Tail came up and it went almost straight down, just as I got the lift back it pancaked in the high grass (wont do that again for sure) and of-course the prop stopped dead,, a bit of glue and bend the struts back straight and back in the air and after a few minutes the Engine quit,,, Broken Valve Spring,,
I don't have the Spring compressor so I can't do it myself, but I have the Head off now and I will send it in to have the Springs replaced..
