1991 12.5 kohler comand in aSimplicity Broadmoor
been having this issue for about 2 years now.
Just had the Carb rebuilt, new fuel pump, fuel lines, fuel filter
mower wouldnt start for 4 days, tried every day until the battery dies. tend to back fire or not fire at all. I took out the plug , turned the engine over and there was spark. Put the plug back in and it would backfire. Took plug back out and no spark. I assumed it was fowled. bought a new plug and it still wouldnt start. Finally, 2 days ago it happened to start right up, I let it idle for about 15 minutes and shut i down. Wouldnt start for another 2 days. I finally got it running again and jumped right on and started mowing, it ran geat for 10 minutes and BOOM!! backfired out of the muffler, Bogged down and died. An hour later It started with some efffort. I proceeded to mow for the next 2 hrs without an issue. After mowing I parked it in the garage.....Now im on day 3 of it not starting again. It either back fires or does nothing at all............It ran great for a couple days after I had all the repair work done to it but now it's back to its same old problems.
just hopng for any suggestions, I was tempted to buy a $50 coil toight just because. Ive gotten to the point where I want to start replacing things until the problem goes away......or talk to sart people that have educated ideas.... Thank you or reading my long rant and thank you for any help you can offer, Jon
