I have replaced the points and remote mounted a gas tank. I had no fuel in the bowl so I freed the needle. I then started the tractor and guess what...... It's the same!!!!

So all the kohler guys that will be at ball hollow better pack their diagnostics kit, cause the tractor will be coming with me.

Sounds like you solved your problem yourself. Your needle or float hanging up. Get a spritz bottle with a small amount of gas take the breather off start it up when it acts up give a little spay of gas see what happens . The finer the gas mist easier to keep running if it is your bowl running out of gas . Like dropped82 said I've got one that the float tang was twisted dropped in shipment or maybe drop kicked. One other thing do this test out doors . That's the fastest way I have found to troubleshoot between gas or electrical.Just be careful when spritzing the gas . best of luck getting it going .

I had a Kohler carb that the needle would stick into the seat every time you turned the gas on.  Bought a new needle seat set, and solved it.  The old needle looked perfect, but I noticed the old seat had a larger seating hole, and that caused the rubber tipped needle to wedge into & stick.  NO problem after installing new, and BTW, the new seat had a much smaller seating hole.

Chris, that has crossed my mind but I'm to the point of just stepping back and letting someone else go thru it a little. If it is the head gasket I would be very surprised because it has excellent compression, and I has a gasket give upon me on another k301 and it was pretty obvious. I'm not sure what is wrong with the engine but I am certain someone at plow day will look at it and tell me exactly what it is and fix it in under 20 minutes....

I dont think you can get an accurrate measure of compression without the use of a manometer because of the ACR, easiest way is to spray carb cleaner around the edge and see if it smooths out

Can the needle and seat in two different carbs do the same screwy thing? So how would I know if it is the needle seat, the spraying gas in the carb while running??

If you have a rubber tipped needle, it should have a pretty small seat hole.  The larger seats are for the solid metal needles I believe.  Someone just put a new needle in mine, and used the old seat made for the solid needle.  Buying a new "set" should eliminate that issue.

See, it is a new carb, so I would expect those parts to be ok.

Crazy question. When I had the bowl off there was a rather weak spring in the bowl to hold the float in the up position........ Why the heck is that in there, and could it be causing an issue, it isn't a powerful spring, but still there.... Wonder why I put it back in.......

Every Kohler carb I have worked on had no spring for the float. The only thing controlling the float was the gas entering. I'm wondering of that spring is the problem. Even with a fuel pump the float needs no help in closing.

I would pull the bowl and eliminate that spring. After doing that check and make sure your float level is correct. Then see what happens. It sounds to me your ignition is good. Considering nothing changes when you adjust the carb leads me to believe its your culprit. If the electric all was the source, carb adjustments would still affect it. If my sons football schedule works out I will be at Daniel's plow day. I can spare some time to look at it. After I get my plowing fix of course lol.

On a better note, following this thread tonight kept me up long enough to finish my painting on one tractor I'm hoping to take with me. I'm gonna thank you tonight but maybe not in the early morning while heading to work lol. Good luck!

Eric, you are killing me, cause I keep wondering about the carb, but the first one was doing the same thing so I bought a new carb thinking that would fix the issue. I still have the issue, and I'm still unsure what I'm doing (or not doing). It will be about a week before I will get to look at the thIng again though, so I am troubled. That spring is on my list though, and if the bowl is dry when I open it... Then the needle will be out too.


Congrats on the additional painting you achieved.

I've seen them on Onans with the fiber floats . Spraying atomized gas in carb bypasses every thing from valves back to tank. If it makes no difference in running it narrows it down to the valves or elec. When was last time you de carbon head ? should be every 500 hrs with valve to tappet clearance same time. In essence the spritz bottle becomes your tank and carb if no gas in bowl.

I bought the tractor last year and had planned to decarbon the head after I got it running right. Could I be chasing that?

I read a few other threads and everyone on other forums keep pointing to the points and condenser, But the condenser was new last year, could replace it with the new one I got yesterday. And i just replaced the points yesterday. Mabey I did not get the gap right or something.... I don't have the timing hole in the shroud like most say exists in the later ones.

Its tough diagnosing an engine without it in front of me. I usually have to talk back and forth with it a bit to see what's going on lol. In all reality, I always try the simple things first. If your points are gapped at least .020" then you shouldn't have any problems. I have never fine tuned the timing on a kohler and yet to have any run problems. As long as the gap is correct then you should be good. Although I have had a bad spark plug that made my hairline go back farther. It would idle but lose spark on anything more than that. It was brand new! I would do a quick run through on everything. Also try removing that bowl. Does the engine smoke at all while running? Any tapping from the valve train?
