Question about Yard Machines 24a 021h700 4.5 Horsepower Chipper/Shredder/Vacuum, Push Model
I have the 4.5hp 21" yardmachine walkbehind and mine is doing the same thing. The govenor springs are ok. Changed spark plug,gas,oil airfilter. Mine runs high then low to almost a stall and it continues to do that until it runs out of gas. I have contacted a few people and they seem to think its the 2 springs that control the idle speed. Mine seem to be in check. I have tried to adjust the springs the best I can but I feel even if i have them perfect it wouldnt fix the problem. I want to fix this mower only so I dont have to buy another one. But at the same time I dont want to put ANYMORE money into the heep if it will not work. Please HELP!!! Thanks!!!
This is what I would do... Remove the fuel tank and carb assy.. Two bolts, one behind the gas cap and one on the end of the tank. Pull it straight off the intake pipe then unhook it from the throttle link. Now, unscrew the carb from the tank. Clean the carb with a can of carb cleaner. Slip the screen off the pickup and make sure it's clean. Discard the pump diaphragm and gasket. Buy a new pump diaphragm kit, part #795083. Clean the top of the tank where the pickup with the screen fits into. Put it back together. Remember to put the rubber diaphragm against the tank and the gasket on top of it then the carb. Don't forget to attach the breather tube when you're putting it back on the engine. That should fix 'er up. Also, if the rubber ring and plastic retainer ring came off on the intake pipe when you pulled the carb and tank off, put them back in the end of the carb before sliding it back on the intake.
