K301 won't run fast
Ok I'm mess'n with a K301 in a 102 and it starts good and idles smooth as a sewing machine. No smoke and no extra noises. Try to rev it up and it sounds like it tries to seize up. If I don't throttle back it will kill it. Bring it back to idle before it dies and it runs smooth again. Sometimes it will rev up ok with no problem. I should mention too this is a black replacement engine in this 102 and had sat for many years until yesterday when I brought it home and got it started. Can someone tell me what might be going on?
Oh after it warms up oil starts dripping from the crankcase breather. Valves? Cam? Timing?

Could be starving for fuel on throttle up. What do you really know about this motor... is it a "never used" rebuilt motor that sat around a long time? Trying to pin the oil drip as well as maybe fuel issue.

I'd rebuild the carb ,make sure its set correctly. clean the tank and sediment bowl, check the timing. then see if it improves.
take the breather off and make sure its put together correctly, make sure the mesh is in there. you probably have high crankcase pressure that's causing the oil out the breather but check it first

I really don't think carb or gas issues has anything to do with it sounding like it's going to seize up. It's not like it's running out of gas and it's not missing out. The engine is pulling really hard. Its almost like you're driving along, engine running full throttle and running as it should, then all of a sudden it comes over a load like someone engages a huge brake until it dies. Kind'a like a 560 diesel running strong and hard on a dyno and pulling it down until you kill it. The K301 doesn't take long to die after it starts coming under the load, maybe 5-10 seconds. But if I pull the throttle back quickly to idle it will recover.
 The engine was used after it was installed as a replacement in the 102.

Sounds like something is wrong in the piston/cyl.
maybe sat long enough to rust the cyl or it was set with too little clearance. If it were mine i'd be removing the head for a look see, before more damage is done. oil blown out the breather indicates blowby from improper ring seating.

I am also gonna go out on a limb and say it's a fuel related issue. I would also check the point timing and see if a valve might be hanging open when it warms up.

I had actually just got this tractor and got it to start. The PO had tried several things that could have been the issue for not starting. I should add the guy I bought this from ( a member here ) saved this 102 from going to the scrap yard from the original owner. I found the neutral switch on the clutch was the main problem for not starting along with dirty electrical connections on the ignition switch and solenoid. I hadn't thought to check the points of timing before I tried to get it started. I found the points were fouled and barely opening. I don't know how it even started or ran. After setting the points at .020 then setting the timing using the static method the engine starts right up and has know hard running issues at idle or full throttle. The oil coming from the crank case breather ended up being a bad gasket. So I made a new gasket and no more oil leak. I didn't have to touch the carb. This is turning out to be a pretty good day.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
