Bitter learning curve. Absolutely DONE with carburetors!!!

Since I have changed the fuel pump I have two things that never happened before, it stalled a couple times in the driveway backing out of the garage, but did not stall after that. Also when I got back it gave a little cough when I shut it off.
So my plan now is- I changed the spark plugs, the plugs that came out are too lean, and I'm not starting it again till I drive it to Pagan's, this way he can see the plugs if he wants when I get there. Hope he can get me straighened out.
