In reading the many pages of carb information on this site and reading your response I am beginning to think this carburator is unusable on the 289. I originally had a 600 Holly on the engine and it ran quite well except it constantly had the usual leaking issues and related Holly problems. I was thinking this 600 flat top would be a nice replacement and of course might need jetting and some misc tuning but would be functional once sorted out. Can I make it work? I also have a new factory fuel pump with filter canister that seems to put out a lot of pressure, could this be contributing to the problem? Would it need to be regulated (I never had to before) it seems to hold pressure and the float level is not too high.
Finally, I also have a very nice 6CAF-F 1.08 carb. Should I scrap this 600 and work on the 1.08 carb for better reliability and drivability?
Thanks for your great help...D.C.
