Hey all, new to the forum, looking for advise... I am a trained Small engine Mech, though I never worked on the field, just spin wrenches for fun. So I am out of practice a bit... Question, I am working on a friends Dixon ZTR with a kohler CV14S in it. The problem is this... It Runs GREAT, mows GREAT... though seems once under load and warm, it will just die out. Seems like a fuel delivery problem, as, you can keep it running for a short time longer when it starts, if you put it to full choke. Then after about 5 more seconds, it just dies all together. The warmer it is, the more often it does it. Here is what it is NOT: It is NOT carb (has been cleaned and rebuilt, I found a spot for a welch plug that was not installed, but you know how carb kits are (for several models) so I left it out as I found it.... It is not a fuel cap/venting issues. Has a new fuel filter, the in tank filter is fine and cleaned. The fuel pump is clean and in great shape, seems to work well. I am thinking possibly a seal/gasket somewhere that is getting warm, expanding causing a lean condition? Or some sort of electrical condition that once warm, and resistance goes up is causing problems... any help is greatly appreciated... Thanks!
