TUNED BY WEST FOUR STROKES
index008015.gif
The Tuned by West Magnums have modified heads giving them approximately 20% more power, and
modified carburettors installed directly to the head giving them snappier throttle response, easier to start, eliminating flooding when inverted.
 
West Eurotech tuned Magnum 120F/S
Quote by Steve Dorling (Aviation Modeller)
 
"A bargain performance package"-that`s Steve Dorling`s view of the Weston UK - modified Magnum 120 four stroke
"Starting was so very easy and ultra dependable and at no time did I have to resort to the electric starter"
"Capable of giving performance equal to or better than similar products costing a lot more"
"It is a powerful, reliable, sweet sounding, smooth running and beautiful handling piece of precision work"
"It goes straight into my top drawer of best engines"
"The sheer improvement in handling and convenience makes it a worthwhile exercise alone"
"Equipped with the West carb and manifold just a couple of chokes proved sufficient for an immediate
hand start every time"
"Throttle response was markedly snappier"
"The Magnum 120 is something of a bargain"
"Forget your starter motors with this one-they are no longer required"
 
West Eurotech tuned Magnum 180FS
Quote by Phil Gutteridge (Model World) review of CML Otop
 
I have been running my Tuned-by-West 180 and originally started with the same prop i had on my Saito 180, namely an 18x6. The Saito just handled this prop, but was not comfortable on an 18x8. Your motor was so far under-propped on the 18x6 that I changed to the 18x8 and now have a 19x8 on it!! It is as sweet as a nut, but I think that a 20x8 would be a more sensible prop to load up the motor and allow it to develop its full potential. The downside is that it uses more fuel to produce the increased power, so i may have to fit a bigger tank and buy more Prosynth 2000 10% to run the thing! Your new silencer is very effective and easily meets the noise limits on the field.
 
West Eurotech tuned Magnum 61FS
Quoted by Mike Le`Mmon (RCM&E)
My little tuned by West Magnum 61 4 stroke has proven to be very reliable and powerful. The adjustable carb mounted directly on the head has eliminated any tendency to flooding when mounted inverted in my 3 D`er. Used in conjunction with Prosynth fuel the Magnum 61 still looks as good as new. After substantial use this engine and exhaust still perform like new. What a cracking combination!!
