How to spark test leaf blower - Poulan/Weed Eater No. Bvm200le 711482 24cc Gas Blower/Vac

Test for spark when it is warm. You may have a damaged ignition module.

You can take a spark plug tester and plug one end into the spark plug wire and the place the other end on the spark plug and pull the starter rope and see if there is a spark present. Hope this helps.

ITs hard to diagnose these things over the internet, it could be so many things.
Is this a gradual loss of power? If so; Im sorry to say; that it sounds like its losing compression as it warms up. It is not cost effective to repair the unit.

If the loss of power is more sudden it could be a failing ignition module. Ive even seen spark plugs that quit working when they get hot.

To test this you will need a proper spark tester, laying the spark plug against the head will not provide an accurate assesment, and a can of carb cleaner. Run the unit with the air box cover and filter removed till it fails and immediately give a shot of carb cleaner in the carb and restart. If it starts right up it could be fuel related. IF it doesnt start right up then quickly test for spark. If no spark then its likely the ignition module. If it wont run on the extra fuel and it has spark then it has probably lost compression.

The unit uses a magneto system. To test the module remove the black wire from the module then reassemble unit and test for spark ( spinning by hand will not work, you need to use the starter rope to get the needed RPM to create a spark). If you have no spark with the ground wire disconnected the module is bad and needs to be replaced. If you DO have spark with the ground wire disconnected then you have a pinched wire going to ground or a bad stop switch

remove the small wires from it and spin the engine over if still no spark the coil is bad

Try a new spark plug. If you have done that and still no spark, check the flywheel coil leg gap (.012) thousand, should do it. Also, disconnect the kill switch and run a spark test again. If the unit still doesn't have any spark, then in all probability you need a new coil or as they call them today, a new module.

Check spark plug. remove the spark plug, clean it and test it. If it still doesn't start, take the spark plug out, and connect it to spark plug wire and try to crank the blower, and see if it makes a spark, if not you may need to replace the spark plug.

Unless you have fiddled with the carb, it's not the carb. Check spark with an in-line spark checker then check compression with a compression tester...if these two test good THEN it may be the carb. If you need to know how to use those tools or where to get those tools, let me know here.

How did you do the spark test? Did you use an in-line spark tester? You need to determine definitively that there is no spark and the only way to do it is to use an in-line spark tester...you can get one at Harbor Freight for about $12. After you've checked it that way, if there is definitely no spark, most likely the ignition module is faulty. You should be able to purchase a new module through Sears Parts but bounce the cost and time of that off of the cost of a new blower...you may be surprised.
