Near the end of last summer my lawn boy would not start. After checking for Spark and noticed no spark. Put a new plug in it and still no spark. Any ideas? I assuming the coil or something could be bad. Not sure how expensive this could be but I had to put any more money in such and old mower. I do like the mower though.

Check coil and condencer, clean points, and check for bare wire. I have seen wires rub the flywheel and ground out.

Sounds like you need a new coil. You can get one off eBay for $20-30, and they are not hard to put on. Take off shoud, and you can see easily see coil, and replacement is easy. Replace it just like it is installed. Use a business card for spacing between flywheel magnets and coil. I am certainly not a small engine mechanic, but have replaced several of these, and they were fairly simple.

What is your model and serial number?

10201 silver series. I will have to look at it to get the serial.

I had the same mower. The ignition coil has gone bad. This is a weak spot on the Lawn Boy. Very simple fix once you get the new coil.

OK , if you have a defective coil and your model is a 10201 built 1993-1995 with a V motor 4-4.5hp the coil part number is 684049, 92-1152,99-2911, and the latest number 99-2916 is available from LB for $57.94 or many after market suppliers, such as R&S Equipment at web site outdoorpowerdeals.com or you may call them at 1-800-409-0162 . Their price for 99-2916 is $17.95 including shipping. Monday - Friday 9-5 CST

Another thing to check is if the mower has a blade/engine kill cable. The cable usually applies a brake to the crank but also kills the ignition.

Hey thanks for the help. I will pull the shroud off and look for loose wires and bad engagement cable. If all is well I will order the new coil. Looks like Amazon has them for $20.50 and someone else posted a link for $17.95 including shipping which sounds like a great deal.

Purchased new coil and installed last night. Lawnboy runs great again. Is it me, or do you find all other mowers to be clumbsy to use in camparison to a 2 stroke lawnboy? Mine is not self propelled os it is super light and can be operatored by one hand. I find it so much quicker to trim my lawn with because I can back it up and menouver it so much quicker than my big heavy 6.5HP self propelled craftsman. Man I love that lawnboy.

Another question. Waht blades are you guys having best luck with? I keep finding the stock blade with the tipped up wings on the back side chip away within a year or so.
