149 power loss when in gear

[Tater305]

I think we need to go back to basics being you said you are a new person I have to ask. You say it looses power then stops are you actually talking about the engine or is the hydro slowing down and stopping?

Already asked... He says its the engine Dropping RPM

Just to let you know. It was the carb. I took it off and cleaned it and it seems to run stronger. Now the funny part is when going up a hill it would still stall out and eventually die. Sometimes its the simplest things- low fuel.

Thanks for all the suggestions.

Just throwing this out there.
When was the last time it was decarbonized,
and valves adjusted.

And howdy, welcome to occ.

Good question. Neither on both. How do you decarbonize? Seafoam?

Here is some information from Kohler dealing with products like sea foam:

Can I use additives in my engine?

We do not recommend using additives or cleaners in the oil or fuel system. Air-cooled engines operate at higher temperatures than liquid-cooled automotive engines, and additives developed for automotive use may not perform properly at higher temperatures.
In addition, oil additives can prematurely break down, altering the properties of the oil and leading to extensive internal damage or failure. Fuel system cleaning additives have a tendency to separate and turn acidic, causing damage to fuel system components. We do, however, recommend a fuel stabilizer during periods of non-use (one month or more) to retard fuel deterioration.

sea foam is a cleaning additive. I've tried it and had poor results.

The best way to decarbonize a Kohler engine is to remove the head. A Kohler service manual has the instructions on how to dicarbon an engine.

Thanks- the last thing I want is to make things worse. I’ll let you know how it turns out.

I have been using Marvel Mystery Oil in the gas on one of my IH Cub Cadets for close to an year. I can't see any difference in the way the spark plug looks or the way the tractor runs. I'm not planning on using it anymore.

I use plow days and pulling a 6-13 car barrel train for testing different things( mainly fuel). I will take 2 fuel cans-one with gas straight from the pump and the other container is my experimental gas to an event. I tried sea foam 2 times at a plow day. both times my 149 was down on power and my 100 would run out of power. Both tractors ran great once the seam gas was dump and pump gas was added to gas tank.
