4.10 should be good for towing. I was worried it had something like 3.08 or even a 2.X set.

Check the float for being saturated with fuel. Sometimes one will start to soak up gas and quit floating. Result is a over full bowl.

Check the float level. Since you say it seems rich, might lower the level a bit. Hopefully, your book has the proper level.

Don't remember if the inside or outside is the 'dirty' side on a Q-jet filter. Since it is out, replace with new.

Your lever is in the inner hole. If all else fails, might try the outer hole. Sometimes less gas is the answer.
