Allan - Most small engines that run equipment that is left to run unmonitored that I have seen use the wind off of the fan blades on the flywheel, assuming it is an air cooled engine, to blow against a vane inside the flywheel housing. The vane has a spring that counters the action of the wind on the vane so that, at a given RPM, the vane position is constant. The engine throttle is linked to the vane. If the engine tries to over speed the increased wind will pull the throttle closed. Conversely if the engine speed drops below a certain point the spring force countering the vane will open the throttle. The spring force is adjustable and therefore one can set this "poor man's" governor to keep the engine RPM at a certain speed. Your engine may already have this system in place and may just be missing the linkage parts between the governor and the throttle. If not I would check with Tecumseh or possibly your local lawn mower repair shop to see if the necessary parts may be available. The parts should be cheap and the installation pretty easy.
Barry Have a small gasoline engine from an old go-cart. It's a Tecumseh with a horizontal crankshaft. Was thinking about pairing it up with a generator to have a small mobile power source, but not sure how easy it will be to govern the engine to run at the proper RPMs. Any ideas? _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
