Tubes and Hanger questions....

(1/3) > >>

WideTrack:
A quick question on "tubes".  Can someone please take a look at the attached photo and tell me if I'm correct?  From outboard to inboard, these tubes are:

Secondary Bleed Tube, aka "Secondary Tube", which should be .036 ID in recipe 2

Pull Over Enrichment Tube, which should be .055-.059 ID in recipe 2

Main Well Bleed Tube.....  What should the ID be on that tube in recipe 2?

Also, Cliff says for recipe 2, the secondary metering rod hanger should be "G or higher".  Does "higher" mean higher in the alphabet or bigger going down to the letter A???  My hanger is an "N".  Is that "higher" than G?  May be over-thinking but better now than later.....I had another question but now I can't remember.......

Thanks everyone for your help, and to Cliff for a great book.  I read it several times and just about everything finally clicked after I got my carb apart to look at.  Book's a little dirty now though....

Frank400:
the outer tubes are the secondary POE tubes.  Then, the other ones, which are large, are the primary  POE tubes.  Then, closer to the center of the carb, the smallest ones, are the secondary bleeds, which Cliff recommends to be at around .036 (his recommendation).

WideTrack:
Thanks, Frank, so no "main well bleed tube" as in page 126, or is that just another name for them??

Cliff Ruggles:
The smaller tubes with the tiny restriction in the end are the main well bleed tubes.  They have been given many names over the years, secondary emulsion tubes, secondary bleed tubes, etc.  They are the only tubes that hang into the fuel supply passages to the secondary fuel nozzles.....Cliff

WideTrack:
Got it, thanks Cliff.  Will be ordering parts, I'll email you as well.
