92 ext 550 main jet?

Ok. So I think I found the issue with my sons sled. I think the fuel filter is/was plugged. I pulled the fuel pump, cleaned it and put a new kit in it. Replaced the impulse line (was OK). And new filter. Now I’m checking out the carbs. Trying to determine main jet size. How do I know the size of the main jets I have in the carb? The chart on the sled shows I should have 330-340. I can’t tell what I have in the carb! I have the jet out but there are no numbers on it. The numbers I can find on the carb are 38E 232.

As a reminder this sled was hard to start hot/cold! It needed to be choked to start it hot!

Please let me know what I’m missing!
Thanks
