in the last year/season, there has been alot of efforts/testing done on a particular model carb known as and based on the weber 32dft 2 barrel progressive

prior to that, i wasn't interested much in a scc after glancing over info out there on the topic, over the last few years

i was inspired by the recent efforts of joedrum and then westgl,

i will also be fiddling with an assortment of weber 32/36 series variants, including the holley 5200 series
as well as a single barrel 30 pict

there is already a ton of recent/current easy to find info on the 32dft and intake options using a vw plenum

as i understand, prior to the 32dft, (32/32 & 32/34) most other 2 barrel efforts were based on the 32/36 series stuff, with mixed results,

the 32dft was a known carb but only used by a few, now there are many more

i doubt there will be anything quick about this, i will plod along as time & interest permit, plus there is a ton of easy info out there already

lotsa info here, http://www.goldwingfacts.com/forums/2-g ... nt.htmlthe good part is starting with a brand new weber based carb for 90 bucks, there are even cheaper rebuilt options,

you just need a vw plenum and hook it all up
http://www2.cip1.com/ProductDetails.asp ... e=C13-3241
one prob that has come up is there appear to be 2 plenums out there, only one is a known easy mod, prob has to do with this part
This center section when used with the C13-3244 manifold runner tubes will complete the manifold system for all 1700cc to 2000cc 72-79 Bus Type-4 style engines. With C13-3244 - replaces the ACC-C10-5501

i'm gonna start with a ford 740 variant available in ford escorts, best easiest choice would be the carb westgl is using

some facts and history
http://www.randakksblog.com/single-carb-conversions/

what some folks have been up to,

this link is using a brand new good to go (jetted right so far) 90 buck weber based 32dft
http://www.goldwingfacts.com/forums/284 ... st612.html
I was able to get the bike running very well for less than $ 150. This includes carb, manifold, runners, air filter, and shipping.


other recent quick startup runners option
how to build "1 cut" pvc and rubber plenum to factory elbow intake runners.
http://www.classicgoldwings.com/forum/viewtopic.php?f=107&t=6963&sid=d24f21c66ec635b7cf55434768983cc7
http://www.classicgoldwings.com/forum/g ... cf98d19367

i have ~ 5-6 carbs at this point, prob gonna start with (the 90 buck new, known good to go aka) tom's carb
32 dft variant that came on ford escorts,

in the mix is a new single barrel pict 30 clone along with an assortment of 32/36 based weber/holley 5200 series stuff, a mix of new, rebuilt used etc

from what i've run across so far, imo, going down this road is mainly for folks handy with tools and able to go there and tinker

hey wgl good to hear from you! i'd like to hear more about where you are at now?

feel free to continue here, we are basically working on the same thing and i sorta lost track of where you are at exactly from your initial runners, not sure if going without heat is gonna work for you, or how things went, or she ran as the temps came down

i have 3 32dft's at this point, 2 are ros (rebuilt old stock) that went for 50 bucks apiece and look brand new, they are for an 81 escort application and look to be 32/32, primary/secondary

the 3rd is used for 85 std escort and looks to be 32/34 that went for 25 bucks, prob i'll rip into that one first to get the vitals.

i'm gonna stick to those for now in this thread then go on to 32/36 stuff where i have a new empi dgev that went for 130 bucks, a genuine dfev weber that came with air filter, plenum and a few runners all of it off a vw setup ~ 60 bucks

got a holley/weber 5200 32/3677-80 2300 pinto (prob auto tranny) for 10 bucks
a ros h/w 5220 for 78 CHRYSLER 1.7L

last one is 30/31 pict new for 65$ and i still need to get a 'joedrum choke' of course
lots of this stuff goes on ebay with best offer options that i'd encourage pursuing

here's whats come up so far, all wesgtl's info and efforts have been based on one major known, and that would be what some folks are calling tom's 32dft based carb, iow, you know what you are starting with from available info, jetting should be the same etc http://www.langdonsstovebolt.com/store/ ... id=1222026

when i looked at the new 90$ carb, first thing that came up was shipping for that alone was ~ 40+ bucks, then possibly xtra for customs, so decided to go even cheaper with rebuilt/used and got a few motorcraft variants that were on ford escorts 1.6 - 1.9 engines years 81-86, one actually went for 10 bucks on ebay

i would say that going that route is starting with a can of worms with who knows what to start with, from ebay purchases, not much is adding up as far as pix, info, there were changes along the way, differences for auto/manual trannies, you are pretty much starting from scratch in what you may have bought vs consistent knowns with tom's carb

so i'm ptob gonna fiddle with the new single barrel pict along with the new dgev 32/36 twin barrel progressive empi first

when the weather warms up.... + my stockers are/were still humming

I have been looking at doing a single carb conversion but have been fiddling with the idea of how to go about getting everything to work together.
watching this close with hope one can come up with sucess and put out a complete parts list and a diagram/pic of how it goes together (for idiots like me)
