1932 (31) PA got here, and the sorting out BEGINS

Recommended Posts

i put 400 pretty good miles on my roadster last summer .i think i got around 12 or 13 miles to the gallon. i ran it up to 57 mph . i can idle it down to like 300 rpm.my tail pipe is a little sootier than i would like but it did not foul plugs. i did get the vacuum control figuered out. maybe that helped . it has orig. correct jetting per manual for the DRT-08 209-S and my carb has the 209-S brass ID tag. maybe this is the answer .probably has more horse power and good gas milage. this is not my engine. just found the pic on line.

That pic looks like the intake was reversed and is using a downdraft carb.  I wonder what kind of carb it is?

It appears to be the cheap Ball & Ball Carter downdraft favored by Chrysler Corp. I am not 100 percent on the identification.

 

Obviously, identification would be a tad easier if the air cleaner were not present.

Hello BB and all , man time flies . Well after my initial start up .by enlarging jet hole only . And the problem BB and Broker-Len had with fuel consumption  ie running maybe rich . I decided to finish the idle tube mod to spec by reducing the economizer jet down two drill sizes . The carb had to come off anyway ,as i had noted intake and exhaust leaks at manifold . So had to order gaskets and then hand planed manifolds to within 20thou . A warp was most of my leak . Also added ferrules to exhaust tubes . Next was the leak at the exhaust pipe ,then at the clamps . I never had a tailpipe . Muffler had turn down on exit just behind cab . So decided to hand bend tailpipe and fab OEM tailpipe hanger . Finished that and was hating to take carb idle tube out again since it needed to be sealed with Seal-all every time . 

   So new plan envolved something to fix that . So first reduced constricted area ,(economizer) which stretched length a tenth inch . Before cutting found out by dry fitting , was  never going to work . A inspection with 10x eye loop show where it was drilled out and not straight either . Solution , mill to 1/4" and install with o-rings . beautiful . Seals and removable . Back together and weather turns cold till now . So Sunday started . And it was harder starting . probability because of leaner . Full choke barely helped . Why ?  Because same gypsy removed the choke system components . All was left is sliding new solid cone . So once it was warmed  test ride was good . Ran quieter , because of exhaust repairs and carb preformed as good as my Zenith . Maybe nicer on acceleration .

   Next job ,after a few honey due projects is modify standpipe and install missing choke system ie two springs , brass sleeves and ring ,cone with vacuum internal release , and standpipe chimney slide shut off . Got these parts off ebay parts carb DRT181 ,  I think . I'll keep you posted .

   Anyone have a choke cone from 209 , would be interested if there are numbers on it . Number mine is little different then spec . sheet ? What a project ,err . Nice to be retired and quarantined .

Hey Tom, I have attached a few pictures of my choke cone collection.  The 58A-38's  came from my DRT- 08 209S  The others I extras I had .  I think I destroyed an RJH  a long time ago and keep some parts.   The 58A's are little bigger in diameter and have 2 small vertical slots in them .  They are 58a-38 but my DRT08 209S illustration  shows a 58A-37S

Would not happen to have the correct low speed jet tube would you ?   11-120S ?

Sorry, no low speed tube.     In a phone conversation Tom said there were some other low speed replacements for the 120'S

Yes, we have been trying them out but am still on the look out for the correct tube. I drilled out a chevy tube to correct specs and it runs and starts and idles OK but still lacking

Yeah , 31plymouth the cone i have is from a DRT maybe 181 model it is number 58A-34 . They all look to be the same . Where are the slots you see ?  I wonder if number diff as to do with vacuum release strength of spring inside cone or something . If your interested in trading one of your 38's for a 34 . Since you say from 209's .
