Briggs OHV Engine - adding speed control

[Jeff]

I have a Briggs OHV (Intek?) snow engine, Model 12c113 series. The engine doesn't have a speed control, that is the engine is either running full tilt or it is off. (I'd say throttle, but I believe all engines have a throttle, they're connected to the governor, and a speed control would manipulate the governor, not the throttle directly.) Other 12c000 engines DO have an adjustable speed control and indeed there is blank plate on mine where it would be in other versions.

My engine doesn't seem to like to go to full power immediately when it's cold, and I'd like to run the engine at idle speed for a few minutes after use to melt off any snow before shutting it down. Having a remote cable to the handle isn't important.

How hard would it be to add a speed control lever to the governor on my engine? I believe the part number I'd need is Briggs and Stratton #

691028 .

Thanks!

I'm not familiar with that particular engine, but if it follows previous designs and there's a coil extension spring visible in or around the throttle linkage, what you'd do is rig something to change the position of the "fixed" end of that spring.

Moving that end in a direction which lessens the tension in the spring should slow down the engine's overned speed.

HTH,

Jeff

Thanks. I'm planning a purchase of a bunch of engine parts soon, so I'll order the speed control. (I think the bolt/nut are sold separately). I figure it should be easy to connect since I'm not doing any hackery--it's an (optional) actual part of the engine design. Beats me why the blower manufacturer didn't include that with the snow blower, it's not like it's a generator application that *needs* to run at full speed. Of course the reason is probably the same reason it doesn't have a fuel shut off or (maybe, didn't check) a fuel filter. Maybe I can rectify that too--it's a pain to have to drain the tank somehow just because you want to fix/clean the carburetor.
