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 .
