How do you fix this??

Nothing to be stumped about.
Without the blades engaged or fan blowing there is effectively no load on the mower so it chufFs along happily.
When you put a load on the engine, the engine slows down so the govenor should allow the throttle to open further.
Yours is obviously not doing this and you were told to check this a while back but obviously have not bothered to do so or if you did you did not bother to tell us .
You were also advised to check the pipes for even amounts of heat signifing the engine was running on both cylinders, again with no response from you.
If this is the level of communications you have with the "experts" no wonder they are stumped.

My response in post #3 answers the governor question, however, I thought my answer in post #6 would address the cylinder issue but YES there is even amounts of heat from the pipes.

The engine is brand new. Leak down test and vacuum test have been done and there are no issues with the engine.

# 6 post
Leak down test, tells you good compression, vacuum test, vacuum leak poor low speed. Then how was these test done?? It takes more then this to fire a cylinder. You still have fuel, spark, and timing. New engine, working for a dealer I find that doesn't mean a thing. You are hoping someone has the same problem. OK what problem. The only thing I see here is the engine has no power which could be many reasons. Fuel, spark, compression, timing, you are missing one of these things or it would run right. No issues with the engine? OK if the engine isn't the problem is something getting seized like a bearing. I guess look for hot spots?

Yes, we manually opened the throttle , bypassing the governor and it worked properly / made no difference is a response
Wih the PTP running I pushed the govenor arm and it returned properly is a response
Yes is not a response.
