Where can i buy a magneto for a leaf blower?
Go to any small engine repair shop and they can order one for you. You could also try outdoordistributors.com or jackssmallengines.com. You are going to find that the ignition module is going to cost about $50.00 at least. Have you made sure that the ground wire is not shorting out? The small wire from the module goes to the kill switch on the blower. If it is grounded somewhere it will not have spark. I would disconnect that wire from the module and see if you have spark at the plug. It could be a frayed wire or a bad kill switch. The ignition modules don’t go bad very often. Also remember that the engine has to turn about 150-200 rpm to get a good spark. Turning it by hand may not produce a spark.
