Hi, I believe the motor needs a ring job. You will have to disassemble and get new rings on the piston. Also look at valves guides they will need replacing. In short , you'll have to get a new motor.
Hope that helps.

Adjusting valves on any warm engine is wiser . Specifications are usually listed for both.

Petrol or diesel?

If you want it to start with a start motor, driven from a battery, my guess is the battery is in bad condition. Normally a battery will perform less when temperature is going down, but an old or worn out battery can't perform at all when it is cold. I would check that first. Just take a good battery to start one of them and see what happens. Then see if you want to replace them.

Sounds like the govenor is messed up. Check the springs on the carb linkage, maybe one of the little springs has come off or broken.

Carb has debris. Take float bowl off and clean and if that doesnt take care of it-clean carb completely

You have a carburetor problem. Stuck float or clogged filter. Gas cannot get into the carb as fast as it is used. Letting it sit for a few minutes will allow the bowl to fill.

It could be a carburetor problem or it may be the low oil cut off switch. Check to make sure oil level is up. If it is check the needle valve attached to the float and the seat. The old carbs used to have a brass seat. Some of the new carbs have a rubber seat and it may need to be replaced. Hope this helps.

How did you stop it? Pull the spark plug wire?
There is a carburetor in there,somewhere.Pinch off the fuel line to or from the carb. I like needle nosed vice grips or a BIG hemostat.
