Holy smokes
Hey truckers, I have a 1968 Ford F-100 with a 390. I changed from edelbrock 600 w/ manual choke to an edelbrock 650 w/ electric choke. I was riding without the choke hooked up but later hooked it up because my truck was smoking EXTREMELY bad. I was hoping the choke being hooked up would end this, but it didn't. I can't figure out why my truck is smoking so bad...I also have a 6-8 psi electric fuel pump...could this be the problem?

Blue smoke means oil burning. Manual fuel pumps work just fine . Your electric pump could be pushing to much fuel into the carb causing you to burn to rich all that gas washes the cylinders down and the rings cant seal hence the blue smoke

Is the 650 new? If not do you know its history? If it started smoking when you put the 650 on, then maybe it is the problem. Was there something wrong with the 600? Maybe you should switch back. You could try a kit.
A new carburetor has solved the problems for me more than once, and it is a relief once you have one.

The 650 came from my girlfriends dad, he races dirt track cars. It came off a 351W. It was running like a charm on that, the 600 had a lot of problems. My truck would not run at all with it on there. I switched to the 650 and it runs fine. It's just smoking very heavily
