    I have md#44 &51 44 gets fule & has spark wont start same with the 51

    I have the same problem, with a model 51. 2 separate plugs will not fire, yet they spark on other saws. A spark tester lights up as if it has spark. I removed the coil, cleaned the flywheel, cleaned the coil, and still the same. I will assume that the coil is weak.

My john Deere turns over but want start

If it's a single cylinder engine, my first guess is the magneto is defective. Other possibilities are defective spark plug or spark plug wire (from magneto to plug). Verify also that the fuse is good.

Hard starting husqvarna chain saw 450 rancher, is drowned

Take plug out of saw, ground it out on metal cylinder, slowly crank saw and see what kind of spark you have. Quick,bright blue fire is good, yellow or huge kernel fire is not. No fire is ignition module. If soaked with gas change plug if that don't do it, it is time to put a kit in the carberator.

Troy built tiler won't start!!

What is the method your machine uses to decide when to fire the spark plug? Does it have a magneto, and/or ignition points under the flywheel, or a crankshaft postion sensor?

Riding mower wont start

Hi Pry

The spark comes from the Magneto. Follow the spark plug wire and you will find the magneto at the end of it

The first thing you should check though, is the safety kill switch. There is a pressure switch in the seat that kills the engine in the event the driver falls off.

You need to be sitting on the mower to start it.

If the switch is ok and you still get no fire, it's the magneto.

Best regards,

It wont spark at all. No fire. Just put a new spark plug so that's not the issue. This lawnmower is only 1.5 years old. Thanks

Could be magneto bad, wire from magneto bad, ground on magneto bad, or the clearance between the flywheel and the magneto is rusted up if it was outside. Clean flywheel with sandpaper and set magneto gap using a match book flap.
