Does not have any compression! Was running fine, then gradually started slowing down and loosing power and died. Tried to start it and noticed when you pull on starter rope there was no compression.

Sounds like the rings are gone. Either that or the connecting rod has broken. Probably the rings. You can get a replacement part from a local small engine shop. Good luck...Lee

How many rpm's is it running at when you first start it up and it is running on the choke? Does it gradually start to idle back and then start to die r does it do it all of a sudden and dies?

When running with the choke on, it is on the high idle circuit of the carb, as it warms up the idle should slow down and then idle in the 800 rpm range in Park, 650 in Drive. This will be the low idle circuit range. This transition inside the carb will cover an idle air bleed hole in the venturi of the carb and lean out the mixture. If you notice that the carb smells gassy and black rich unburnt gases are coming from the tailpipe, the problem is located within the carb and requires a carb tech to do a rebuild of the carb. You could try a good carb cleaner like Lucas by putting it into the gas tank, in case you just got a bad tank of gas, but that is just a bandaid for a more deeply rooted problem. Get the carb rebuilt?

Honda mower hrr 216 pda starts up fine, runs about 2 minutes and dies out. I remove the carburator, took it apart and cleaned it, cleaned out gas tank and replaced with new gas, new air filter and spark...

Hello Frank,
I would purchase a compression tester from your local parts store. Check compression when unit is cold, then run unit until it dies. When it dies, immediately check compression again. If reading are close to the same your problem is probably not internal. If you loose a lot of compression once unit is warm and dies, its probably internal and will need to be torn down.(compression should be at least 60 psi if not more) If readings are the same, I would purchase a spark tester and check before and after again to see if your loosing spark once unit is warm. If compression and spark are both good before and after, problem is most likely carburation. Hope this helps. Good luck and happy wrenching!

Engine overheats, loses power, starts back up but dies when put in gear

I hate to tell you this but... If it overheated you probably have at the very least blown a head gasket. The best thing to do is run a compression check and that will tell all. Hope that helps

Riding lawnmower loss of power, runs ok at first but in 1/2 to 1 hr loss of power, replaced fuel filter/fuel kit

you need to check compression. sound to me that ether the valves need adjustments or you have cylinder damage causing compression loose when engine warms up. send me the model# of the mower and engine too.

What causes compression loss on a 1998 yz125? could power valve stick open or closed causing this? it was running fine and gradually has to be pull started. once i get it running it will not open up. it...

Pull started? on a YZ 125?
The power valve will not allow high RPM power if it is gummed up.
Low compression is due to bad rings, a different problem.
You may have both problems.

Loss of power at 2400 rpm's

Check your mass airflow meter. If it's bad, at least on my 1990 300ZX, the car won't rev over 2400RPM (it's a safeguard built into the ECU of the car). Grab one from a scrapyard and swap it in and see if that fixes the issue.
