Sounds like you have a blown valve. I'm assuming this is a 4 stroke motor, if it was 2 stroke then it would be the reed valves. But either way it's the valves.... unfortunately that will require a mechanic :(

Hello blumph,

I can think of only one or two things that are causing your problems. It could either be approx. a $14.00 switch in the handle that has shorted out, or 2 bad brushes $1.75/ea.on the armature (motor). Both are fairly simple fixes with just a screwdriver and maybe pliers. You might also check and see if the power cord has been chafed or damaged and is shorting out. 

See below for parts:

Microwave blows fuses


A short likely in the wiring for the light or at the safety switch embedded on the side where the door closes----be careful as a 20 amp fuse takes something major to take out.
(for it to blow)

This might be best left to a qualified service person.

1992 gmc pickup keeps blowing heater fuses I replaced the blow motor and it keeps blowing


Have you replaced the blower resistor . some times they can cause the fuse to blow . You may need a muiltmeter to test the current draw on the blower motor circuit. the draw should be less then half of the rated fuse .( 20 amp fues draw is less then 10 amps) You did not say but does the blower work on high only or the lower speeds with out blowing the fuse ? if it does work on low or high with out blowing the fuse i would replace the blower resistor

Starts and runs good but after an hour of cutting when you turn off.. then you want to cut again it will start just fine but when you engage the blades the fuse blows it has a 20 amp fuse is this the right...


I normally see 30 amp fuses to the deck...but it depends on which mower you have. If you place a larger fuse and it does take a 20 amp..you may burn something up. I would check the blades, spindle towers and clean all the stuff on top and inside the deck to look for something catching on the blades. www.nnyparts.com

Fuel ECU fuse keeps blowing (30 amp)


Your fuel pump is internally binding and causing the fuse to blow. Change the pump (and filter while you're back there.)

sounds as though you are on the right track
but be sure to check the wiring directly from the electric clutch on the front of the motor back to the switch
a wire could be pinched in the frame and shorting out intermittingly
look around and find those wires and move them around and look for chaffing and tightness
and what you could also do is to unhook the clutch at the connection to it at the front of the motor and engage switch and ride around and see if fuse blows and if not you may have an electric clutch issue
