Add a spring to the springs (#3) to add tension to the left belt around the pulley because it is longer than the distance around the shorter side of the right pulley.These springs can get weak over time,and that will make the left side slip easier than the right side.This is why the factory...

I only know that it works for me.I had a generator that had been sitting for several years,and it would run with fresh gas when choke was on,but died when it was taken off.It could reach top speed with the choke on,so I add some ATF and started it up,let it rev to full rpm,then held my hand over...

Do not use a torch-tip orifice cleaner..they have notches like a file,and they will enlarge the orifice,creating a non standard fuel ratio that cannot be adjusted out.Use a straight pin or needle that will just barely fit the orifice.Blow carb cleaner through all holes to check for blockage. I...

The total length of the blades is not necessarily equal to the the width of the cut because they are mounted in an offset angle from each other. Make sure the blades are mounted in the proper direction:(not upside down). This could affect the uplift of the blade.A solution may be to install 3...

A "RS" or "2RS" suffix is a rubber sealed bearing.The "2RS" is sealed on both sides.A "RS" is sealed on one side only..A shielded bearing,like with a "KD",or"KDD" bearing is a shielded bearing,It is designed to keep dirt out,but not keep grease in.A Sealed bearing does both. The inner shield or...

There is a very small spring that is parallel to the governor spring.It seems to do nothing,but it takes up the slack in the governor spring hole to prevent surging and hunting.It prevents what they call hysteresis.Hysteresis is good in some cases,like a pipe wrench for instance,the sloppy fit...

To get the max hp,it must be run at the specified speed.The fan for cooling is part of the equation,and most air cooled engines run cooler at rated speed than slower speed because of higher oil pressure,more air flow. At the speed you are running,it should not have a big effect,unless you are...

HP is rpm X torque.HP is more important than torque itself,because torque is only one part of the equation.I have seen a 1/16 hp electric motor pull concrete anchors out of the floor,but it was geared like a clock motor...very slow. Most (but not all) small mowers are rated at 3600 rpm,so hp...

There is an impulse tube from the crankcase to the carb that uses pulses from the crankcase to pump fuel to the carb.These impulses operate the diaphragm in the carb,so make sure the impulse tube is not cracked,clean, and not leaking air.This can cause the exact problem you describe.

The rust and trash in the fuel cutoff solenoid can physically jam the solenoid and prevent it from working properly.The seat switch is a common problem.Put a jumper across the wires of the switch and see if that solves the problem.If so,replace the switch for safety. Kohler had lots of problems...
