Engine dies when I engage the blades???

[Hardluck]

having not start and run issues again. Changed fuel, filters checked all safety switches?

How do I check the ignition module? Or does the mower have an ignition module or just ignition colis?

im having a similar issue but mine runs fine but as soon as i pull on PTO in 14 seconds it will bog down to 2700rpm and stay that way for 8 seconds then ramp back up to full power for 14 seconds then bog down again for 8 seconds

5 pages in and I still don't know what engine you have. Lots of talk about 30 minutes old which doesn't mean anything.

Could be a twin running on one cyl that dies when you hit the PTO.

This has been sitting. Most likely a carb or fuel delivery issue.

they told me they put new plugs new coils, new fuel lines, said the carb is fine, adjusted the valves ,, and it still does it. Kawasaki FR 731v engine not even the dealer can figure it out

sounds a lot like my issues, it is probably something very simple and over looked but I can't figure it out.

Well sounds to me like the dealer has no idea about what they are doing or are telling you porkies
IF it stops dead it has to be in the ignition system or the electrical system
Some thing simple like a burned out diode or dead short in the coil or if it has a control module ( not familiar with yur mower ) a bad module or plug .

Sometimes you have to go with a gut feeling. I had Kawasaki V twin in the shop back in the Spring that would die engaging the deck. The idiot ignition jig said it was firing the plug so ignition should had been fine. Well after even thru having the pulling of the PITA muffler to check valve rockers and push rods, I still had a dying engine. So I when thru the whole safety system still nothing found wrong. Even the new plug had burned the factory plating off the tip indicating it was firing.

Well as a gut feeling I said to myself has to be the ignition coil so I installed a new Kawasaki coil. Fired the engine up and tested. Sure enough it was failing under compression fuel load. When I look over the coil I could see the epoxy was separating from the outside housing of the coil and that moisture was entering the coil pack.

Just shows that something our tests can give us a false indication. This where experience kicks in. Some of us small shop gets more experience than the big boys as we see more abused equipment.
