Question -
When I engage the pto and the motor  is not hot it stalls and does so until the motor is good and hot.  This machine has a new pto, tranny, rebuilt carb, recent tune-up, and new bearings in two out of three pulleys on the deck.  At the moment it needs a new drive belt.  When the motor  warms up it runs fine but until that time it wants to grab when the pto is engaged and stall.  Thanks in advance, Ernie
Answer -
How old is the mower?
Do you have a push/flip button style PTO or is there lever you have to manually move?
I'm not sure of the age late 70's early 80's.  pto style is mechanical engaged with a lever on the side.  Thanks again, Ernie


Let me know.

Answer
Challenging problem.  Does the engine governor seem to work?
This is difficult to describe but when you engage the pto the engine RPM should decrease slightly and then regain normal speed...you should be able to hear the slight difference in RPM.

Do you hear any RPM drop when you engage the PTO?  Another way to check the RPM is to cut some taller grass.  The engine should decrease slightly and then regain normal speed.

Let me know.
