Just rebuilt my carb, it’s on a 289 V8 2 BBL, it use to start with 2 pumps turn the key. Now about 20 pumps then it will start. Carb is getting fuel on every pump. I did set carb to where it was before rebuild when I rebuilt. Once running it runs great and starts immediately when turning key. Is there something I should adjust to make it start easily first time. I have not changed or checked plugs that would be next……please advise
