The red is correct except for the sharp bend at the connection. Inspect for broken strands. Negative goes to a starter mounting bolt or nearby.

October 24, 2024 -

Bought a Craftsman DGT6000 (2003) and few months back as running but poor with exactly 500 hours. Found it had a bad head gasket and replaced both of them with Kohler parts. New plugs, fuel filter and air filter and a fresh oil change. Compression is within spec. But if I engage the pto and try to drive, it loses power and will die unless I turn the choke on. It'll sit all day with the pto engaged, or i can drive it around all day with zero issues, but it does not like doing both at the same time. Will start to bog down and will stall if I don't choke it. Will run ok with choke on about 50%. Also replaced the fuel pump. Took the carb completely apart and it wasn't dirty at all. Put it back together and got the exact same results. Ordered a cheap carb off Amazon and out that on and it ran even worse. So I decided to rebuild the oem carb with the Amazon carb and still no change. It just seems like it's not getting enough fuel and idk what else to do.

Usually something like this is that one side isn't running- usually due to the ignition. If you have a temperature gun, aim it at each exhaust pipe and you will see a big difference in temps if that is the case. Ignition parts you have to be careful and use the model and spec; as there are 3 different types of systems. Even then, you have to then know what supersedes what.

Check valve clearance and see if the rockers are fully opening the valves. See if the governor is moving and working by pushing against the arm when running. I don't know if you have the $500 carb w the accelerator pump or just the common 2 barrel, but if the mechanical stuff is working then the only thing is a fouled carb that can cause a lean issue.

I’ve seen it happen before on a kohler command. I replaced both coils and it ran great. You filled at the gas station, rule out, unless you have a clogged fuel filter.

I have a Simplicity Legacy 25hp (sub-compact tractor) with a Kohler Command Pro. It has 1100 hours on it, so its by no means a new tractor.

It has a problem now where it will run for 35+minutes, cut really good (no extra choke or anything like that), then suddenly bog down and die. it starts right back up but immediately dies as if its getting no gas (choke helps it stay up for a little longer but not much)

I've tried

New sparkplugs
gas cap off (vapor lock)
running each cylinder individually. It starts with either cylinder running seperately but still dies immediately after.

both cylinders get spark. The fuel filter has gas in it.

It doesn't smell like gas, get red hot, or make any smoke but the muffler is in pretty poor shape (original from early 00s) and it sounds like a cammed muscle-car so im guessing that is causing some extra heat. but i feel like there must be something else going on. So im wondering if anyone here has any other diagnosis steps i can take to pinpoint the issue?

I really dont want to take the carb off if i dont have to, so im planning on running a fuel cleaner. aside from that, maybe new coils?
