Hello, I have 2 of these here that I still have to look at.
One takes 4 pulls to start.
The other is hard to tune.

They can be difficult to get right.

I would check your governor set up again.
When you reassemmbled it was the governor shaft all the way to right, then place the governor arm on the shaft so that it is all the way to the right, please see image below.

I have had your problem before. I re-adjusted the governor arm on the shaft slightly. Check it all moves as it should with your finger.

Also are the carby gaskets sealing and not sucking air.

This manual is available from TORO's website.
