A couple of years ago I bought a rebuilt Carter YF 2100S and put it on my stock '57 235. It must have been an older rebuild as I had to replace the gaskets due to a little leak. All has been good until recently. When starting cold in the morning I used to be able to choke and the engine started easily and warmed up fine. Now I can only choke a little and then I have to close the choke or else it runs way too rich and rough. I have also gotten a couple of backfires after slowing for a stop sign and then trying to take off....only one little pop and then it's fine. Gas mileage is also starting to decrease as well.

What do you think....time to rebuild?
