we have a new sno blower will never buy from sears again had to repair it myself they don't stand behind there guar any more like they used to== my question is- has anyone found a way to put a throttle on these so they do not run at such a high rpm all the time it is uncomfortable and wastes gas besides going too fast I don't want to spoil anything but think there must be a way to have a throttle like the older ones-- PS this is a great site and has not failed me yet blw

The linkage on those are probably preset to run at a constant speed. You may be able to loosen the linkage on your engine I did it on a B&S engine on my Troy Bilt tiller. I have a Toro lawn mower that has that feature. I stopped the engine when I'm not mowing and restart it when I continue mowing. Hal

I run a Craftsman 24" 2 stage. It has a throttle and 4 forward/one Reverae. Throttle systems are different on each model/engine combination sold. The throttle plate in the carb is operated by a bent wire from a governor. The governor is usually internal (air vane, or inside the crankcase with fly weights) There is (with enginuity) almost always a way to get at the spring controlling the applied force.
A fixed speed engine will have a fixed spring attachment. Making a bracket that allows a range of tension to be applied with a throttle cable will work. It would be easiest to find a real lawn mower/small engine shop with real people in charge to assist in retrofitting the control. Do not make it direct pull, it will have too much travel. They usually have a 4 to one leverage or so, that requires 4 times the control travel compared to the spring travel.
Do not make the spring control such that the spring is stiffer, or stretched farther than the original. Jim
