I have a McKellar circular saw. I was ripping up some old pallets for firewood. and thought the blade had jammed. I stopped, took the blade out of the work and tried again and the motor goes and the blade turns for a second or two. Then the blade stops turning but the motor noise remains unchanged. I wait a bit, and the same thing happens. The motor is OK. The switch is OK
What do I do?

It is very likely, that the fixating screw/disk is loose. Do not operate the saw in this state. It is dangerous.
A circular saw usually has a direct drive. I.e. the motor spindle is also the center shaft for the blade. So if your motor is spinning, but not the blade, it means the blade has lost contact to the shaft.
Check if the blade is properly centered and aligned with all locating pins (if your saw has some). Then fixate the screw using the appropriate wrenches.
