Hello, new to this forum looking for help with my Lawn Boy 8237. I got it at an auction with two other mowers for 15 bucks. Out of the three this was the one I had the least interest in as it was very dirty and in pieces. As I cleaned her up and put her back together my feelings changed. Such an odd looking machine that I started really liking it. She has good compression but no spark. I checked the kill switch and spark plug both of which are good but the coil is not. I got one from Amazon but it did not fit. I looked on line and have not found a coil specifically for the 8237 mower. I asked several sellers that state the coil dose fit the 8237 to verify that it fits and was told if it looks like the photo it will fit, but it dose not. Can anyone help me find the correct coil for my 8237? I am looking forward to bringing this old girl back to life. thank you!!

what is your serial number from engine or mower please?
https://www.partstree.com/parts/lawn-boy-681578/ This is just an example, possibly not your coil. You can go a step further & google "Lawnboy part number", for best price, be careful as you want original Lawnboy part, not from Amazon made in china.
Depending on serial # & year, let us know how it goes, thanks, Mark

Thank you!!!! Let me go dig it out and we will see where it goes from there.

Does it look like this?

Serial number from mower is 9489725. I checked parts tree for my coil 681410 and came up obsolete. I checked the diagrams on parts tree also, turns out she is from 1979, no luck with having a coil available though.

After looking at the diagram again, it is showing 681578 as the coil for my mower. Not sure what the difference is between the 681578 and the 681410 but I am willing to give it a shot.

This looks similar to my coil, mine is white in color. From what I have read some of these coils have to be grounded to run and others have to be open to run. If that's the only difference then all I have to do is flip the wires on the on and off switch. I am fine with that. I am going to keep on digging and see if I can find some more info. A big thanks to everyone for their input!!!!!!!!!!!!

Ok, looks like I have two options here. Not knowing the history of this machine the coil in her may not be the correct part (who knows who was monkeying around here before I got her) and I can get the 681578 witch parts tree says is the correct part or I can get the 98202 witch looks like a match for what is currently in her. I am going to dwell on this for a bit.

I ordered this one https://poweredbymoyer.com/products...awn-boy-683215-682702-683080-f-series-1983-up As I believe the difference is with working being grounded or being opened. That will be easy to deal with. Will keep ya posted on my results. Thanks guys!!!!!!!!!!!!

I remember from many years ago and owning a Lawn Boy that after spending big bucks to buy a new coil, usually the fix is to use fine sand paper and clean where coil mounts and the coil mount locations. Worked every time. Good luck.

I checked the ohms, unfortunately it was no goo. thanks!!

Problem solved!! I wanted to thank you all for your help!! The new coil did not look like the old one but the magnets and mounting holes were the same. I had to modify the engine cover a little but she has good spark and fired with starting fluid. Awesome!!!! Thanks!!

Update. I cleaned the carb and air filter, new spark plug. Wired in the on-off switch. Buttoned her all up, hit her with one more shot of starting fluid ( she sounds great!!) . All ready to put some gas in her and enjoy the fruits of my labor. All in I am at about 30 bucks invested, we will see if I decide to pretty her up, for now she is ready to go. Thanks for all the help guys!!
