This is obviously just a guess but, it may not have been anything you did. I just did an autopsy on a SV840 that had locked up for no apparent reason. The gear that drives the oil pump and the Woodruff key were laying in the oil sump. All the internals look fine except the crankshaft is stuck in...

Yeah, I repaired it and used a zip tie to keep it up off the edge of the baffle. I looked at the rest of the harness for possible trouble spots then moved and zip tied anything that looked like it could rub. Thanks again.

You absolutely NAILED IT! The carb solenoid wire was rubbing on the metal baffle. I couldn't see it until I moved the wire as it was pristine on top but worn through an the bottom that was resting on the edge if the baffle. Thanks for the help! Hugh

I'm thinking stator. On the longblock swap it was pretty straightforward. Moved stator, flywheel, coils, fuel delivery, muffler, etc from one block to the other. Does the fact that it runs fine for 30 minutes or so give you a clue as to the fault? Thanks for the help!

Hello all, I'm working on an old (2009) Bad Boy Pro 27 with a Kohler 27 hp. I did a longblock swap using a used longblock and the original accessories including charging system etc. Mower preformed perfectly for several hours then began blowing the main fuse. I traced the issue back to the...

Without a receipt, it will just be store credit!🤣

I would suggest checking battery voltage with a meter with PTO off and as you pull it on. Also, repeat with the deck belt off. See if the battery is weak and drops or the PTO is going bad OR if the load from the deck is a problem (ie seized spindle/ idler).

Very first thing that I did.

Thanks, I have verified the key is not sheared. I have tried starting fluid BUT I didn't think to open the choke after setting it to start for the initial test. I have good spark on both plugs. I will start over today.

I understand and I don't get mad at anyone trying to help. I was trying to give you as much info as possible as to what I have done. I have been using in-line spark testers with plugs installed. I will re-check everything mentioned. Thanks again.

Ok, thanks. I have set magneto gaps to .010". Re: the carb shut-off, I've tried starting fluid directlyinto the intake manifold. No difference. That's what lead me away from fuel issue. It has good compression turning by hand, I had ruled out valve adjustment solely b/c it doesn't even try to...

Thanks for the info. Now, as weird as this sounds, I have good spark with the kill wire removed (only 1 each) BUT now I also have spark with it attached. On both coils. And still no start. Additional info: my buddy says he replaced head gaskets sometime last summer and it ran fine but he says...

Troubleshooting a no spark issue. Engine spins over. No spark. Both coils test good, checked for sheared crankshaft key, tried a known good voltage reg / rectifier, new plugs. One thing that I do NOT know on Bad Boy / Kohler is which (if any) safety switch will allow the engine to crank but cut...

Sounds plausible. It is a new carb but that certainly doesn't mean anything. I'll try that. Thanks!
