I use a regulator set about 6 psi (I also have a gauge just after the regulator).

I am shopping now for new oem type fuel lines since I kinked two of the links at the carb while removing them. The oem type are a PITA, but they look good and I like the stock look. It is a tribute car after all. Found several guys selling them on ebay, but... the rebuild kits are hard to find. I am looking for Holley part # 3-396 or 37-396. 


I noticed my inboard list # is 4670 (it also has 2360 stamped next to it), which according to a model # list I found is for a 1971 440 auto trans flowing 355 cfm. Wish I had the manual version (#4669) but I cant imagine there's much difference.



I stopped by NAPA and I ordered part # 2-5529 which appears to be the right set, but for $37 it probably wont be. 

Ill pick it up tomorrow and start comparing the parts, though OI have no idea the existing gaskets are correct. Its not like my carbs were running perfectly. They were very rich. Idled ok, but always a cloud of smoke when I punched it.

Any suggestions as to power valve and jet sizes? 

Currently running jets at 80 and power valve is either 8 or 8.5

Jets in the promax equipped outboards are 86


Ok, now I need to know how to remove the floats. I unscrewed the two hinge screws but it wont come out. Is there a hinge pin hidden back there?


or just to check for proper operation. The floats seem to operate ok, but the reason Im rebuilding the carbs in the first place was because my engine was totally flooded. One or more of the three inlet valves failed to shut


and another thing, how many questions do I get?  

A few more:

After studying the exploded diagrams and browsing ebays offerings, I realize none of my 3 fuel inlets contained the cylindrical filters and springs? like these:

 Are they needed? Im thinking the lack of those bronze filters may have at least contributed to my problem. They seem like a last line of defense against any small bits of debris.

And if I have to pull this whole setup a few more times changing jets, etc, I will probably ruin my new set of $45 fuel lines, so I may put together a temporary rubber line setup until I have everything running just right.



PS

figured out how to get the floats out. Need to wear my "reading" glasses more often.
